Does this hand look ok to you guys?

Villain is 60/2 over 124 hands. We are $200 effective.

Villain limps BTN, Hero opens 76hh in the SB to $8, Villain calls.

Flop ($18): Qs Th 8s Hero c-bets $9, Villain calls.

Turn ($36): Ks Hero bets $22, Villain calls.

River ($80) 4s Hero bets $40

OTF, can I use a smaller 1/3-pot sizing here? If so, would I want that for my value hands as well like AQ, KQ, QJ, QT, KK, AA, TT, etc?
