NL 100 - AQo flops TPTK

This is NL 100 on Prima so the converter won't work.
Villain is 30/6. Seems semi-loose preflop, playing alot of suited connectors but can handle himself after the flop. The only hand he has shown down is limping UTG with 7 [img]/images/graemlins/diamond.gif[/img]6 [img]/images/graemlins/diamond.gif[/img] and checking down with the blinds.
I'm 23/7 when this hand comes up. I haven't shown down anything, just stole the blinds.

NL 100 6 max
Hero (UTG+1)- 97
Villain (CO)- 89

Preflop - 1 limp, Hero raises to 5 with A [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/diamond.gif[/img], Villain calls 5, 2 folds, limper calls 4

Flop (pot 16.5) - Q [img]/images/graemlins/heart.gif[/img]J [img]/images/graemlins/diamond.gif[/img]7 [img]/images/graemlins/spade.gif[/img]
Limper checks, Hero bets 14, Villain calls 14, limper folds

Turn (pot 44.50) - 9 [img]/images/graemlins/spade.gif[/img]
Hero checks, Villain bets 14, Hero calls 14

River (pot 72.5)- 2 [img]/images/graemlins/spade.gif[/img]
Hero checks, Villain bets 28, Hero calls 28

I feel like this is a terrible line. I thought it was way ahead/way behind because I didn't think KT or T9 would call preflop and possibly not the flop either. Should I lead the turn and fold to a raise? I felt like I was getting value bet by a set, but didn't want to fold with those odds. Flop bet should be around pot?
Thanks for the help.
