I've played about 2 loops at the table, opponents all seem loose

Preflop: Hero is MP3 with Q[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/spade.gif[/img].
UTG calls, <font color="#CC3333">UTG+1 raises</font>, UTG+2 calls, MP1 calls, MP2 calls, Hero calls, CO calls, <font color="#666666">2 folds</font>, BB calls, UTG calls.

too loose a flop call with 1 limper, the raiser, and 3 cold-callers?

Flop: (16.50 SB) 8[img]/images/graemlins/club.gif[/img], J[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(8 players)</font>
BB checks, UTG checks, UTG+1 checks, <font color="#CC3333">UTG+2 bets</font>, MP1 calls, MP2 calls, <font color="#CC3333">Hero raises</font>, CO folds, BB folds, UTG folds, UTG+1 folds, UTG+2 calls, MP1 calls, MP2 calls.

Obviously have to at least call here, getting about 19:1 with a gutter and backdoor flush draw... Raise to get a free card/pick up some outs? (admittedly queens might not be outs here) Just call?

Turn: (12.25 BB) 7[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(4 players)</font>
UTG+2 checks, MP1 checks, MP2 checks, Hero checks.

Anyone bet here with the double gutter?

River: (12.25 BB) 8[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(4 players)</font>
UTG+2 checks, MP1 checks, MP2 checks, Hero checks.

any other comments?

Final Pot: 12.25 BB.
