When, and with what to take a stand?

$10+1. UTG was extremely loose and passive. He has shown down K3s and T6s at different times.

BB (t870)
UTG (t1040)
MP1 (t2855)
MP2 (t785)
Hero (t475)
Button (t1145)
SB (t830)

Preflop: Hero is CO with J[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img].
UTG calls t100, <font color="#666666">5 folds</font>, BB checks.

I'm getting pretty low on chips, but this is only the second hand of level 4, QJo is not a hand I want to be called with, and there is a limper (although an extremely loose one who has limp-folded to raise behind).

Should I have taken my stand here?
