Not going to be a particularly insightful response, but its better than nothing...

As with everything in poker this is going to depend on your read of villain and your estimate of his read of you. I don't usually double barrel unknowns, but if you're going to fire twice this is a pretty good board to do it on. Rainbow with a couple of straight draws, but the turn couldn't have helped him any. A 2/3+ pot sized bet (I'd bet $15 or so, but make it consistent with your made hand turn bets) seems legit. Obviously, fold to any resistance and if he just calls then spike the K on the river and bet the pot.

Rereading my response gives me the general impression that its worthless, but absent some reads its the best I can do. Perhaps thats why I suck at poker?
