should i play this top pair harder?

[ninja please]

party 1/2 game. no read on any of the relevant players.

i'm in LP and am dealt JcQc.

UTG raises, and it's folded to me. with no players in yet and against an UTG raise, this can't be a good call. but i call 2 cold. in my defense i was playing 3 tables for the first time today (usually only two) and was in another hand at the time, so i wasn't paying attention like i should have been.

folded to the blinds who both call.

flop: 4d Js Th

blinds check, UTG bets, i raise, blinds call 2 cold, UTG calls.

turn: 9s

blinds check, UTG bets. can i raise again? any big pocket pair has me beat, but he may also have AK or AQ. but i did pick up the open ended straight draw. of course he could just as easily have KQs. anyhow, with all these thoughts, i just call. so do the blinds.

river: 6d

blinds check, UTG bets, i call, SB calls, BB folds.

UTG shows AQo, and i take the pot. SB had J8.

other than the pre-flop call, which i realize should have been a fold, how was the play here? can i reraise on the turn or river? or should i be calling at all on these streets?
