[Q] About to flash Kernel - Galaxy S II Q&A, Help & Troubleshooting

Hello, coming from a Nokia user, this is my first time using android phone.
My specifications:
Mobile version: GT-I9100
Android Version: 4.0.4
BaseBand: I9100XXLQ6
Kernel version: 3.0.15-1060868 (The damned Kernel, thought it's an unknown chip on Chainfire's app and a sane chip on the other app)
PDA: LPJ
PHONE: LQ6
I am concerning the bugged stock kernels of 4.0.4, so I decided to flash Siyah kernel version 5.0.1 using Odin.
Please recommend for me the version of Odin and supervise the whole process, and how risky it may be.

There are enough of tutorials on how to flash a kernel via Odin. So feel free to use the search button.
Its simple and safe. Just ensure you use the TAR version of siyah 5.0.1 while flashing via Odin.
EDIT: @above- the link you posted is for the i777 not i9100. They have different key combinations to be used to enter download mode. For the i9100 its Vol down + home + power. Please do not mislead.

3 Questions: (I am paranoid ) Q1: Will the Siyah 5.0.1 go compatible with the STOCK android 4.0.4?
Q2: Will flashing this kernel lead to data/apps loss?
Q3: Is it compatible with the leaked JellyBean?

We're all paranoid when we're screwing around with our phones the first time around. But if you follow the tutorials properly, you have nothing to be worried about.
1. It is. But if you're installing a custom kernel its usually to install a custom ROM. So why exactly are you installing siyah if you plan on sticking to stock 4.0.4?
2. No.
3. I don't think so. But if you install the leaked 'official' JB firmware, it'll replace whichever kernel you have anyways. So unless you're planning on installing siyah AFTER installing the leaked JB, this shouldn't be an issue.

I just want to get rid of the stock kernel, and root the phone(back my stuff with titanium before I get the JB or a custom ROM).

Oh man. I really need a point in the right direction. I've been reading all day about this, but I'm worried I'll totally stuff things up if I proceed with out confirmation with what I'm doing.
I received my GS2 from Kogan website yesterday, followed the "How to Root Galaxy S2 i9100! [ICS]" (sorry can't post direct link yet) now everything is great, however the bluetooth with not turn on. It doesn't go bright green when switched on, it stays a dull green and then turns off again. AAAARGH.
Origional Kernel . 3.0.15-I9100XXLPQ-CL223505 [email protected] #3
Current Kernel. 3.0.15-1060868 (CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5.zip)
PDA: LPJ
PHONE: LQ6
BaseBand: I9100XXLQ6
Is this fixable? I've tried really hard to find the origional Kernal so I can put that back on with ODIN. Or should I put Siyah Kernel on?
I had lite'ning ROM on my last GS2, though was wanting to stay a little more stock this time around, as it's not vodafone branded.

Big thanks to Faryaab, for his great work. Will shout you a beer.
The separate kernel was no longer available. So I put put I9100XXLPQ_I9100OXALPQ_XEO on with ODIN and it's all back to normal.
