I don't see a problem with the limp, this to me is a good sign that you are looking for profitable situations to play rather than focusing on a chart.

I would raise this turn. There are a lot of cards that are going to kill your hand on the river including any spade, K/9/J/T. You have position and there's a good chance you have the best hand right now. Depending on the reactions of your opponents you can safely call a reraise (with your 4 likely outs) and fold the river unimproved if it's 2 bets to you (and probably call 1).

This would also make the river action more straightforward because here your hand is underrepresented (the turn call makes your hand look like a draw).
