8h 10h from the BB in 10-20

[Kenshin]

I am sitting at a 10-20 table at pacific poker against 3 other players (2 decent, 1 unknown). UTG folds, button calls and the small blind raises. At this point I make the dubious play (is it?) of calling with 8 [img]/images/graemlins/heart.gif[/img] 10 [img]/images/graemlins/heart.gif[/img]. The flop comes down 8 4 2 with rainbowed with one [img]/images/graemlins/heart.gif[/img]. SB bets, I reraise, button calls, SB reraises. Is it correct to call this raise. I put the SB on an overpair. A heart comes on the turn and I check and call. A miracle heart appears on the river and I check raise. I believe I played the hand correctly; however, I am not certain about the initial call and the 3 bet call.
