Party 50nl 6 players - Did I maximize value with this hand?

[CarlSpackler]

Recently, it seems like I haven't been getting payed off as much as I'd like when I've got a monster. Is there anything I could've done differently this hand, or is this pretty much standard? The villain is pretty laggy. Shoud I have bet the turn instead, or made a different sized bet on the river? There's $16.50 in the pot on the river.
