I might have raised on the flop. It's quite a weak lead from UTG ($5 into $15 pot), but if your read is right, this might have to be taken cautiously. The call from the CO tells me he is maybe not too sure of his hand - he certainly doesn't like it enough to raise himself; however, again, if your read is right then he could be stronger than you think but is just not very good.

I'm definitely getting it in on the turn. You still have quite a lot of outs even if you are behind plus I think you are increasing the likelihood that you win the pot here (not such a bad thing) rather than at the river where the rest will probably go in.
