amaturee has been extremely loose with 71%VPIP , 15%PFR, only 38 hands

My questions:
1. Flop decision, good/bad, why?
2. Turn bet, good amount?
3. River = "Negative Freeroll", right? This reminds me of hand from 2005 WSOP ME, Jen harmen's nut boat vs. Cory Zeidman's S.F. So i have to push here, right?
