I'm interested in turn and river comments here

Steal is pretty standard.
Villain seems pretty loose/bad (35-20 after 30 hands), and is likely stinging after a few hands earlier when he 3-bet me with KJ and I called with KK and stacked him on a jack high flop.

He must have some sort of hand to be betting. TPTK? Set? Two pair? Flush draw that hit?
anyway, is a turn re-raise standard for value while I"m ahead? or should I call and let him keep spewing? If I'm scared of an over-flush then I should have been folding the flop. As played river shove is standard?
