Preflop: standard

Flop: You should just bet. You can't be sure that somebody else will bet (you said the game is passive). Plus if somebody bets in late position and you raise you will probably knock players out between you and thats the opposite of what you want. As played I'd just call. If there were others in the hand I'd cap for value. But being out of position you want to be able to checkraise if you improve your hand.
