Flop a set, turn card completes draw?

Reads: Just sat down at the table, but haven't seen either player really get out of line. Stats are not significant, as they are over an extremely limited sample of hands (<25).

Commentary: The turn was a card that I was hoping not to see. But at the same time, for one of the villains to have AK, he would have had to have called with a gutshot on the flop, or he would have to have a 9 for an oesd or a 9T for the flopped straight. While this is possible, I feel like a typical low stakes player could have a lot of different two pair and one pair combinations here. Against a range that includes JJ-99, KQ, AQ, AK, 98s-9Ts, KT and QJ, I have 53% equity on the turn. Does this range need to be tightened or widened in this spot (I feel like KQ could maybe be eliminated if I could assume the player was reasonably competent.)
Since calling the turn means that I have about 24 dollars left and a 28 dollar pot, what do I do on the turn? Given my turn action, what do I do if the river is a brick (like it was) or if the river is a disaster card (a 9 or a K)? As played, I am getting more than 5-1 on my river call, but UTGs bet is real suspicious. I'm pretty sure I have to call here.
