Do I have a value bet here or not?

Party $2/$4. Everyone in this hand is loose, fairly passive and not very good at poker as far as I can tell. I have KJs on the button and raise after UTG+1 and the cutoff both limp.

The flop is 237 with one of my suit. The first limper bets. That doesn't mean much to me, could be any pocket pair or any piece of the board. The cutoff calls and I call.

The turn is a red King. UTG+1 checks, the cutoff bets, I raise, UTG+1 fold and the cutoff calls.

The river is a total blank and the cutoff checks to me.

This feels like a really stupid question but it seems like every decision I've made for the last six months has been incorrect. Who bets here? While we're at it, who limps pre-flop, folds/raises the flop, folds/calls the turn, etc.
