Were my calls on the flop and turn justified?

Will try to give some of my reasoning at the time why I did what I did. I know I made a few mistakes on this hand, but feel some of my calls were very marginal at best.

Preflop: Hero is BB with 3[img]/images/graemlins/spade.gif[/img], 3[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">2 folds</font>, UTG+2 calls, <font color="#666666">3 folds</font>, <font color="#CC3333">CO raises</font>, <font color="#CC3333">Button 3-bets</font>, SB calls, Hero calls, UTG+2 folds, CO calls.

Mainly calling the flop due to CO's raise meaning nothing since hes steaming about the last pot that I took about 12 BBs off him with AK flopping nut straight and him flopping top set and capping every street with me.

Flop: (13 SB) 7[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], 6[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(4 players)</font>
SB checks, Hero checks, <font color="#CC3333">CO bets</font>, Button folds, <font color="#CC3333">SB raises</font>, Hero calls, CO calls.

Took me a while to make this call was unsure if any of my 6 outs to improve were good, also had to fear a 3bet and maybe cap from CO and SB.

Turn: (9.50 BB) Q[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">SB bets</font>, Hero calls, CO folds.
Decent sized pot easy call still afraid of a raise from the steaming CO. Thought to myself if CO raises and SB 3bets I am dropping my hand
River: (11.50 BB) 3[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">SB bets</font>, Hero calls.

Since I was multitabling I looked at the river and saw it put the gutshot straight on the board and feared if I raises I might get 3bet from SBs flopped straight or higher set. I'd have a tough time calling the 3bet with bot set on this hand so I said why not just call down.
Final Pot: 13.50 BB
