Help Need to update firmware today (Odin), refresher needed?

April last year Kies randomly decided that it wouldnt talk to my firmware anymore so I came on here and you guys walked me through flashing with odin :-) See original thread: http://androidforums.com/samsung-galaxy-s2-international/707139-cant-firmware-update-via-kies.html

I ended up putting a generic LSN version of JellyBean on my Galaxy S2, which was great but its been a bit flakey ever since (reboots quite a lot and poor battery life), so it's time for me to do it again.

I should be fine actually flashing with odin as the guide on here is pretty good so just a couple of questions:

1. What firmware should I know go for? Been looking on SamMobile but not sure what I need. I want an unbranded generic version again.

2. I still have odin v3.07 from last time, will that still do the job?

3. Is there anything else I need other than odin and the actual firmware, and this guide?

Was thinking maybe this one, as my phone was originally from the Carephone Warehouse store and it should now be pretty stable? Plus SamMobile are showing it is now compatible with Kies.
