Probably the .10/.20 games at poker stars would be best. If you find your crushing the game then move to .25/.50 when your bankroll is $150. Bankroll should be approx 300 BB and your kinda in between there so I would start on the low end.
Those games are very beatable. Be happy when you are getting sucked out on and relish the fact that your folding more than anyone else. Play tight but when you have the goods be aggressive as all hell. I'd recommending "Small Stakes Holdem" by Ed Miller for these types of games.
Oddly enough, I find live 3/6 games looser than the online .10/.20 games but they are very comparable.
If you know how to play 7 card stud, either Pokerstars or Full Tilt. I just learned to play this past weekend (after reading the 2+2 book on it) and I'm crushing the micros at both sites. I thought I was a decent Omaha player but the Stud at both of these is just too easy.
