Bottom set from blind fills on river...your move

[DrPublo]

Party 200NL 6max. Villain is pretty unremarkable, I haven't particularly noticed him which must mean he's been keeping to himself. I start with $305 and he has me covered by a bit.

Preflop:
One limper, villain limps on the button and I complete the SB with black 66. BB checks and we see a flop.

Flop ($8): 6 Q 7 rainbow

I lead for $6, only villain calls.

Turn ($22): [6 Q 7] J, putting two clubs up

I lead for $15, villain raises to $30, I call.

River ($72): [6 Q 7] J J

Hero...?

What range of hands do you put the villain on? How do we maximize in this spot? Is there a case for reraising the turn?
