[Q] how/what should I upgrade from my current setup Siyah4.1/ICS4.0.3 - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I have been trying to look for answers in the forum but it is too confusing...My status is like this: I got the phone and installed Siyha 4, that was many months ago, if I look in About this is what I see;
- Android version: 4.0.3
- Baseband v: I9100BGLP2
- kernel v: [email protected]))
- Build number: IML74K.BGLP8
It is working, but it's showing random hangs, GPS does not work many times...and as I see there is even official support for JB, I would like to upgrade. But, I dont know what steps and even what I should upgrade. Not sure if Siyah I can just upgrade without issues, if then I can install any rom I want of top of it...etc. I would be really gratefull if somebody could tell me:
- what I need to upgrade
- in what order
then I will investigate and manage to do it myself. For example, I am after instructions like this (making them up as an example, no idea if this is correct):
1. upgrade to SiyahKernel S2-v6.0beta5
2. restart
3. install ROM cm-10.1.3-i9100.zip
I know there is no 'best' rom, just asking for advise for any JB (or later if there is stable one) rom that works well (no random crashes frquently, GPS working, I really need that).
thanks in advance!

1-to flash stock roms(tar extension) use odin or to flash custom roms (zip extention)then you need a custom recovery (eg ClockWorkMod).
2-if GPS is really matters to you,then dont flash cm10.1 is it have a known issue (gps is not working 99% of all time)see known issues for cm10.1:

if you want stock rom(eg 4.1.2) look here:

if you want custom rom with working gps use(in my opinion)neatrom lite:

guide to flash with odin:

always check the roms with md5sum check.
Hope it helps.

OK, so let's say I'll go with stock rom (I'll remove most of samsung crap with RootDelete)...What about Siyah kernel I installed:
- is it replaced when installing stock rom?
- if not, can I update it to latest Siyah version? should I?

yes,because every rom has a kernel,but if you want Siyah kernel,after flashing the stock rom flash Siyah kernel again.if you want to update to stock jelly bean 4.1.2 then flash latest Siyah kernel.
Sorry for bad english.
