NL noob hand: Trips top kicker - river flush card

[Magior]

50NL 5-handed (sorry, no converter for the site)

Effective stacks $72.
Villain is 30/5 over 30 hands, seems passive

Folded to button who limps, SB folds, I have A[img]/images/graemlins/heart.gif[/img] T[img]/images/graemlins/heart.gif[/img] in BB and check.

Flop (Pot $1.25) 8[img]/images/graemlins/heart.gif[/img] 2[img]/images/graemlins/club.gif[/img] T[img]/images/graemlins/club.gif[/img]
I bet $1, he calls.

Turn (Pot $3.25) T[img]/images/graemlins/spade.gif[/img]
I bet $3, he calls,

River (Pot $9.25) 6[img]/images/graemlins/club.gif[/img]
I bet $6, He raises to $16, I call


Sorry if this is too elementary, I'm very new to NL.

I think I should've raised PF? I'm not comfortable with being aggressive OOP but this is too big an edge to pass up?

Flop and turn bet sizes ok?

Check/call river? I come from a LHE background and it seems criminal to me not to valuebet this but flush draw is a big part of his range and 8x-type hands are not propably calling.
