Im pretty confused by this whole hand. What should my approach have been from the flop?

Edit: No reads on villian but his stats were 26.6/9/1

Preflop: Hero is BB with T[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/spade.gif[/img].
<font color="#666666">3 folds</font>, MP1 calls, <font color="#666666">2 folds</font>, CO calls, <font color="#666666">2 folds</font>, Hero checks.

Flop: (3.50 SB) Q[img]/images/graemlins/heart.gif[/img], 2[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets</font>, <font color="#CC3333">MP1 raises</font>, CO folds, Hero calls.

On the flop i had a decent flush draw, a straight draw and a an overcard. I did bet mostly to win the pot at once but if didnt i figured i had about 15 outs. When he raised i figured he probably had a Q or J.

Turn: (3.75 BB) 6[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, <font color="#CC3333">MP1 bets</font>, <font color="#CC3333">Hero raises</font>, MP1 calls.

Here i wasnt sure what was the best options. I thought that if he had a Q or J he would fold against a bet but also that he could very well check it through if i didnt bet . I did go for the CR and hoped for the best.

River: (7.75 BB) 3[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets</font>, <font color="#CC3333">MP1 raises</font>, Hero ??

Here i was pretty much lost so i just did a panic bet. After his raise i almost knew for certain that i was beat but it was a big pot..

Final Pot: 11.75 BB
