Villain is 52/14/48% over 69 hands. He goes to showdown 47% of the time he sees a flop. He sees the river >90% of the time he sees a flop (21/23)

I have a few questions:
1) Should I bet the turn against an opponent like this or check when the ace hits? I think I played too scared here, since his range is so wide he can have a ton of cards besides Ax. I feel I should have bet for value and protection, and reevaluate if he raises me.
2) As played, do you lead out on the river?
3) Assuming you lead out, do you call the raise?
