Sorry just seen that you posted some more questions. Really it boils down to preference on how you want to root and what's the easiest for you, I did find using revolutionary easy to get root on my 2.3.3, just read on how to root with 2.2 and 2.3 and see which you think would be easier for you and then root that way, both are ultimately going to do the same thing and give you S-Off so that you can install custom recovery and roms.
