I wouldn't raise from the SB. Given the table's perception of you, you are likely get action, which means you'll be playing a large pot out of position with Q2. Especially in PL, you need to exercise pot control, since this limits the size of bets on all future streets. I would limp, bet pot on the flop, and check-call the turn. I don't think you win the blinds often enough to raise, and getting called is pretty much always bad for you, even now that you've hit a seemingly good flop.
