[Q] Need help regarding my SII - Galaxy S II Q&A, Help & Troubleshooting

I have recently purchased galaxy SII (3 weeks ago) and previously i was on a Nokia Symbian based mobile i.e E72..I've been installing lots of apps in my s2 from past 2 weeks and deleting lots of apps which i didn't like..but now im noticing that my sII is becoming slower in performance..It helds sometimes and overall its not as smooth as it used to be when it first came ,im using apps like adavncd task killer,NQ android booster etc to help me speed it up but they don't seem to help much..so is there any way to really maintain the performance and keep it as smooth and optimal as possible??any other good free apps tht can help achieve good performance?
secondly,i have my contcts from previous mobile saved in my pc but i dont know to i should transfer em to S2..any way for tht??i manually added few contacts to s2 and i noticed tht those who had watsapp also started to appear in my contact list rather thn in the whatsapp application..is this normal?
thirdly as i mentioned tht ive been installing lots of apps i wanted to know if there's a particular way i can organize all of the apps that im installing in my s2??i want games to be set in a particular games folder,camera related apps in another and so on ..so is there a way to organize applications in folders??i tried using application folder and folder editor but they showed folders in the application itself not on the application menu bar ..in iphone people simply drag apps on top of each other to put em in folders so is there any solution to this in s2??it becomes tough to manage apps otherwise...i also wanna knw tht in application menu i cant move apps frm one page to another,i can only move them to my home screen..any solution for this??
and lastly i want to know tht right nw i don't have an sd card in my s2 so is it better to have an sd card an put all apps in the sd card or is it fine if im placing em in phone memory??does it effect performance?
im new to android
my s2 has android 4.0.4
not rooted
any help will be appreciated
Thankyou

right firstly task killers are a killer-by using a task killer you are stopping your device caching the memory or reserving it. when you kill an app in that way the os uses more memory to open the app from scratch. i find a swift reboot helps performance. much like my laptop i rebuild/reinstall windows every 8-10 months to maintain performance. i have on occasion after 6 months factory reset my phone just to get the new feeling!
with regards to folders and organisation you can delete folders that relate to apps you no longer have. just make sure not know which one you delete! i wouldn't think this would help with performance but i wouldn't rule it out.
lastly organising apps into specific folders is possible. in touchwiz you can open the app drawer,select menu (lower left button) choose edit, from here you will see folder and page at the bottom of the screen.if you want to move apps to a folder start dragging icons into the folder one by one when done click into the folder and you will have the opportunity to rename it to something other than "folder" same method goes for the page one too- it just allows a much quicker way to organise your app icons in the drawer!
I am using go launcher at the moment and that gives the opportunity to drag icons on top of one another and group them into folders very quickly!

1. I will answer this question last. this is because there other reasons why your phone is slow.
2. Uninstall every task killer. You probably don't need it
3. It depends on how those contacts are saved. so you will need to elaborate on how the contacts are saved on your pc. and their format. Do you still have access to your old Symbian device?
4. This is normal. if you don't want them to show in your contacts, then uncheck whatsapp contacts from the Contact application ( options, contact to display, uncheck whatsapp)
5. Your default launcher, Touchwiz, already has this function, just drag an icon over another. There are good alternative launchers too like Go launcher EX, etc that support this function
6. There is no need to install apps on Sd, except you run out of space. It shouldn't affect performance too.
Follow these steps to improve performance
1. Uninstall apps you don't need or use at all
2. Disable some preinstalled apps you don't use.
- To disable any app,
Go to Settings > Apps > All > Select the app you wish to disable > Force stop the app, then select disable.
Visit here and here for list of apps you can safely disable.
Note that there some apps you can never disable without root even if you wish to do so.
3. Boot to Recovery (Power off your device, Hold Volume up button + home button + power button, release the buttons as soon as your phone lights up)
- in recovery, Select wipe Cache
- reboot phone.
Done.
you should notice performance improvements now.

2)Done,i've deleted all the task killers.
3)I dont have access to my old symbian phone,its dead....Contacts are saved in vCard file format (.vcf)..
4)yeah i've unchecked whatsapp,its fine now.
5)i've figured out how to put em in folders,i can organize apps easily now ..
6)currently my apps are being installed in system storage and it shows that 892MB out of 1.97GB is already covered (although ive remove lots of apps)..I think i'll have to switch to an SD card ultimately coz otherwise i mite experience storage probs in future otherwise..
Question..y arent apps being installed in the USB storage rather thn system storage??what is being stored in USB storage thn and how do i access it?if i want to add songs,i will simply connect usb and add em to the music folder? or theres some other way?
I've uninstalled many apps and disabled some too (those shown in the URL link)..
i've wiped the cache by going in recovery mode too..
i can see significant difference in the performance,i much bttr..doesnt lag much like before ..
There's an app named "gamehub" can i disable it too?although its name is not in the URL link u provided..its a built in app..i dont play games on such apps so i thought i shud disable it,is it safe to do so?some apps start by themselves,is there a way i can control which app shud start automatically n which shud not?
As im new to android,i dont know much about the good apps,games etc...do you have any link where i can see the top apps,themes,personalization,games etc of all times?
thanks a lot man..

Game hub is fine to delete along with readers readers hub and music hub.
If you want ultimate control over uninstalling apps I would suggest rooting your phone and installing Titanium Backup Pro or Rom Toolbox.
You can remove any app (be careful) and choose which apps start up on boot etc. As well as MUCH more.
You have complete control with these apps
For top games simply go to play store. They have a top games section

1. You can simply export those contacts to your android.
- Copy the .vcf file(s) to your phone.
- open your contact application, press options, and select export contacts from sdcard.
2.a) Don't worry about the space until you receive warnings. Applications installed on phone memory are loaded faster.
B.) You can use the pre-installed file manager (my files) to check that. If you are not satisfied with it, you can download third-party alternatives in market
C.) Yes. You can copy them to any folder as well, your music player will find them
3.
A.) You can disable it
B.) I can't tell you will app should start or not. I don't know everything on your phone.
You need Root access in order to disable startup apps
4.) Google playstore (aka Android market) has this function already. If you are not satisfied however, use Google search.
5.) You are welcome
