ladbrokes hand. rip it apart! 5/10 nl

[sisyphus]

5/10 nl. Hero Dealt A Q (Both Clubs)
Ep Raises $50
mp calls, hero calls, sb calls (pot 200)
No real reads, everyone just pretty solid.
Flop, 7 (sp) 5 (cl) j (cl)
I lead out 110
sb calls,
ep goes all in $1,235, i call all-in 1,091, sb calls all in 600.
[pot 3,450]
turn; sigh river; sigh
Ep takes it down with trip jacks,
other had kk.

1. calling raise out of position with aq suited?
2. leading the flop
3. going all in?
comments on all streets appreciated.
anyone bothered to work out my odds? on flop
sorry about format, bison doesnt like ladbrokes
