Obviously reraise preflop, but since you got confused due to the straddle it's no big deal.

I think the only decision is whether to crying call on the river or fold getting around eleventy bazillion to one on our money. You have to be good with the kings what, 4% of the time to make that call profitable? I don't know that you ever are good that often in this situation. However, live I would probably resort to my golden rule of thinking in 2/4 thru 6/12 games: everyone really [censored] sucks. A lot. There's a chance that UTG is no good (despite OP's read) and there's also a chance that he plays KK-99 this way. I'd call.

The other streets were played fine; you were getting the correct price + implied odds to hit your 2-outer on the flop and turn.
