way too aggressive on the flop, way too passive on the river?

Party Poker 3/6 Hold'em (9 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

Preflop: Hero is MP2 with 7/images/graemlins/spade.gif, A/images/graemlins/spade.gif.
UTG folds, UTG+1 calls, MP1 folds, Hero calls, MP3 folds, CO calls, Button folds, SB completes, BB checks.

Flop: (5 SB) 6/images/graemlins/diamond.gif, 2/images/graemlins/diamond.gif, A/images/graemlins/diamond.gif <font color="#0000FF">(5 players)</font>
SB checks, <font color="#CC3333">BB bets</font>, <font color="#CC3333">UTG+1 raises</font>, <font color="#CC3333">Hero 3-bets</font>, CO folds, SB folds, <font color="#CC3333">BB caps</font>, UTG+1 calls, Hero calls.

Should I just fold here? I was hoping that everyone was drawing and betting with marginally made hands, and that I might have a chance at it if no more diamonds fell. Would this situation be any different if I had say... AK?

Turn: (8.50 BB) 3/images/graemlins/diamond.gif <font color="#0000FF">(3 players)</font>
BB checks, UTG+1 checks, Hero checks.

River: (8.50 BB) T/images/graemlins/diamond.gif <font color="#0000FF">(3 players)</font>
BB checks, <font color="#CC3333">UTG+1 bets</font>, Hero calls, BB folds.

Geez I am a sucker here. I know that this in no way warranted a call.

Final Pot: 10.50 BB

Good God man, fold that flop to a bet and a raise in front of you.

Yah, it's different if you have AK. You're ahead of way more hands, obviously A8-Q doesn't beat you then.

Even with AK though (assume no Kd), I'm treading lightly throughout the hand.
