Stars 1/2 - AK on QQ7 board

[JSampras1]

Just wondering if my line on this hand was correct.

Flop better is 29%/15%/1.6 AF, limp/caller is 16%/4%/1.11 AF.
The guy who limp/called 2 on the flop plays very passively.

Anyway my read is it's very unlikely the flop bettor has the queen, because most people would check that. Even if he has the 7 or a PP i have 6 outs, plus BD flush and straight outs, so i think i have to raise right?

The cold call worries me, especially because the flush just hit, but fortunately i have the k[img]/images/graemlins/heart.gif[/img]. This is very easily a check behind right? Of course, because it's me, i miss the river as always [img]/images/graemlins/smile.gif[/img] I definately just check behind here and prepare to muck because 27 donk instacalls here right?
