trips on flop

playing micro pot-limit, I checked w/ A 2 offsuit, only to have a 9 and two additional 2's come out. I bet small as not to scare anyone off. I got two callers. Turn card a queen, bet again and got one caller. River a blank, I bet the pot only to get re-raised. I re-raised only to be re-re-raised and pretty much put all in. I called thinking he had a 2 also, but bad kicker. Turns out he had pocket queens, which were never raised pre-flop.

Did I play right in my re-raise? And should I have figured out he had a boat with him re-raising. Turned out to be a costly hand.
