Your two pair draw sucks here. Depending on how UTG plays postflop, I am inclined to lead out on the flop. The hope is that UTG raises a wide range of hands here, thus driving out the other players, or forcing them to call two cold.

As far as the river goes, it helps to try to figure out what UTG might be thinking. He may think that the river is a perfect bluffing card and so bet again on the river, in which case you can get in a check-raise. He is likely to call you down with any pair. So I'd consider going for a check-raise here, given how you played the earlier streets. There's a chance you will whiff here, but most maniacal players are looking for any reason to bet and will not check behind when checked to.
