Root, custom roms. Questions from an Android noob. - Android Q&A, Help & Troubleshooting

I feels good to be on a phone platform that isn't stagnant. After owning an LG S-Class phone and a Bada phone, having Android feels like Christmas has come early. However I am left majorly confused as to my options on various things.
I have tried to read and understand the benefits of rooting my phone. I've only found one negative in that Google Play movies won't work. Other than that it seems like a great thing to do. However after reading and trying to understand everything, I was left more confused than ever before. So far I've found 4 different methods to root a phone. Which method does one go for? Then there's the super user access, busybox, yellow triangle, again it's confusing.
I would like to root my phone to achieve the following:
- Be able to shutoff various services and things to get better battery life.
- Get access to all of the cool rooted apps out there, like the ones from Chainfire etc.
- Play some of the Tegra games.
- And I'm sure other things I havn't yet discovered or am aware of.
I would like to also know what are the options for being able to install copied paid apps etc. On the iPhone it was easy once you jailbroke a phone, but on Android I'm again confused on this part. I know there is an option to be able to install apps from an untrusted source, but it seems there has to be more to this than that.
Then the thing that confuses me the most is the huge amount of custom roms. Then you have kernels thrown in as well. I've gone into information overload trying to get up to speed with everything and this part seems too large a scope to get my head around it so quickly. I don't have any problem with my stock ICS really, but then I don't know what I'm missing on the custom side of things.
I'm sure I sound like a complete noob. That's ok, I am when it comes to Android. For my previous phones I was flashing custom roms, and doing all kinds of things. Maybe it's not all as confusing as I think, but right now I'm having a hard time getting a good picture on things when it comes to my new Galaxy S2 phone.
I would greatly appreciate someone being able to help me with some of these questions rather than telling me to gtfo or use the search function. I've tried, but now after overloading on stuff, I've taken a step back. I've been trying to find a website, page or post that might answer my questions in a way that I can get my head around it all. In the end I choose an Android phone because of the customizations, and for the community that is doing great things. I'd like to join the party :good:

Superuser access, busybox, and yellow triangle are not root methods. Superuser is what you get when you root the phone, and it allows root apps to get superuser access to do certain root things, if you grant the app those permissions. Busybox is some sort of utility (I don't know much about it, actually. Shrugs) that you can only get on Android once its rooted. Required for titanium backup and some other root programs. I think it was originally on linux. The yellow triangle is a Samsung only thing, basically it counts how many times you have flashed custom firmware and kernels onto your phone. The app triangle away resets the counter so you can claim a warranty if the phone breaks without the triangle giving you away. You can choose your root method, some are one click and others are the traditional method.
Installing the .apk of a paid app? That's a no-no. To answer your question, you can install a non market app without root and there isn't really another side of that. (Maybe you're talking about license verification?)
Custom ROMs are firmware (you know that, since you said you've done it before. The advantages are usually a later version of Android that your manufacturer stopped on, a stock non skinned Android experience (your S2 has touchwiz), and tweaks/other features to make it faster/cooler. For example, ParanoidAndroid allows you to switch between tablet and phone modes easily, and the entire cyanogenmod series has a built in theme engine as well as many options in the CM settings.
Custom kernels (or just kernels) manage the CPU and GPU. Different kernels allow overclock/underclock better battery saver and performance settings, and simply CPU management.

Thanks for the reply gagdude.
The custom roms thing is indeed confusing lol. You have files for modems, kernels, and it goes on. How does one even know if they need a new modem file I wonder. I imagine people probably flash their phones on a daily basis. What to speak of choosing a new kernel.
At any rate, being that this is my first android phone, and my second Samsung one, I'm quite happy with the Touchwiz interface as it's familiar.
I understand more now what a kernel does, unless I'm mixing in some things I've seen that look like a completely different UI. I might look at that at some point, but for now my stock ICS 4.0.3 on the S2 seems quite ok. So really it's now just choosing a method of rooting it.
As for installing the .apk of a paid app, yes that was what I was referring to. It was possible on jailbroken iphones installing .ipas, but I don't know if it is on Android. When you say a no-no, are you referring to it can't be done, or that it can, but it's a topic that cannot be discussed here?

No prob.
Some people do flash quite often, yes, but I don't believe they completely change everything. Usually they flash a different ROM because hey - ROMs are the fun part. Each one is unique and its fun to play around.
Touchwiz is a pretty nice interface IMO but its personal opinion, some people hate it. Either way, your choice on that. I do believe some skins are big resource and RAM hogs, especially Sense (despite it looking very nice) and the old Motoblur. That's when flashing a vanilla Android ROM really helps.
The S2 should be getting a JB upgrade in the next few months, so if you plan on staying stock and taking the OTA, make sure to only freeze bloatware (not uninstall) and do NOT install a custom recovery. Rooting these days are pretty easy, its just that some old timers dislike one click root methods because you don't know what you're getting into and you don't fully understand what you're doing to your phone. Little secret: I've only rooted with one click root methods
Yes just like a jailbroken iPhone you can install the .apk however it is available without root.
When I say no - no I mean we can't discuss it on xda. It's against the rules

Yes I was aware the S2 would be, or should be getting JB in the next few months. I'm more than happy to wait for that. I have found one program that enables you to one click root the phone, but it's a bit misleading as you have to first flash a file using ODIN, thus it's not one click on that sense. What is the program you use for rooting may I ask?
Maybe I got lucky but my phone is unbranded and only contains 2 apps. Both can be uninstalled. As for freezing the bloatware, I'll have to read up more on what services and things I can freeze safely.

SuperOneClick is by far the most popular one click root solutions. It doesn't support all devices, however. If it doesn't work on your S2, that method you found (flash a file via ODIN first and I'm assuming the next step is a one click root?) seems pretty simple. As long as you don't mind doing a few extra steps, there are many methods for the SGS2 because of its popularity. Make sure the instructions to root are for your specific model, becaused there are many variants of it.
The reason why I said not to uninstall bloatware and only freeze is because when you update, you have to have all the apps the phone came with (if its uninstallable stock, then it should be fine), unroot, then update for it to work correctly. Having a custom recovery like Clockworkmod also causes problems when updating. You'll have to stick with the stock recovery.
