Default [Q] T849 from 2.2 to 2.3.3

I have a Galaxy Tab T849. I understand the hardware is the same as the P1000 (USA GSM vs. EU GSM) so I can use P1000 OS solutions.
I have given up on Samsung Keis (won't communicate with Tab) and would like to try Odin. I'm using a PC with XP.
I don't want to screw up
Please point me to step by step instructions. I haven't found them yet by searching.
Stock 2.3.3 would be fine but I'm open to modest variations if they are stable.
Thanks
