[Q] Need help rooting phone - Galaxy S II Q&A, Help & Troubleshooting

Samsung Galaxy S2 I9100(T) Vodafone
PDA: I9100TDVLSM
PHONE: I9100TDVLS3
Android Version: 4.1.2
Kernel Version: 3.0.301-889696 [email protected]#3
Build Number: JZO54K.I9100TDVLSM
I'm having trouble working out what files I need to root my phone as there are so many variations, I don't plan on installing a custom rom I just want superuser access. There does not seem to be the correct kernel version for my phone in this post. http://forum.xda-developers.com/showthread.php?t=1101671
The closest one I think would be GT-I9100T_DUKF2_insecure is that correct as I don't want to brick my phone if there is a chance using the wrong kernel as I don't have a spare one to use until I get it fixed. I have seen people suggest using I9100 instead and flash the modem but I don't want to do that or is this the only way?. I would have posted this in the kernel topic but I don't have the user permission to do so.
I will be using this guide http://reviews.cnet.co.uk/mobile-phones/how-to-root-your-samsung-galaxy-s2-50004972/
Aside from the rom manager https://play.google.com/store/apps/...EwMiwiY29tLmtvdXNoaWtkdXR0YS5yb21tYW5hZ2VyIl0. Are there any other recommended apps that need to be installed after the rooting process

I'm only going to say two things :
1. Search for PhilZ kernel.
2. Don't install ROM manager. It's a safe bet to brick an i9100.

I've got 2 more.
1) Stick to xda threads.
2) Search in the HUGE australian thread sticked in Q&A.

I've got another one:-
If you can't work out how to root this phone without making a thread in Q&A given it was released two years ago, I'd question whether you should be messing with your phone in the first place. Read some threads (which people attempt to circumvent by posting threads like this; refer to my sig as to what happens to these people), settle on a method. It's not rocket surgery.
Edit - And another - If you're scared of bricking your phone, just don't go there. The moment you root your phone, kiss goodbye any expectation of warranty service.

I can work it out I just wanted some verification to determine if I was correct about what secure and insecure kernel I needed before I do this that will allow me to root the phone with out having to flash a modem onto it. I have settled on the method this one. This I why I posted under the Q&A section to get help on my understanding not be redirected to a different thread or told that I should not do this.
