Another simple 3/6 hand played like a wuss -- suggestions?

[Proofrock]

No real reads on Villain except for his stats (19.4/2.8 after a mere 40 hands, postflop aggression of 1.0), I need help playing draws. Particularly in the following situation, my straight hit at the same time a flush hit. How aggressively do you play this? Specific questions on the hand:
(1) Preflop limp okay?
(2) Flop raise seems clear here, but if I'm wrong, tell me why.
(3) Turn: I expect to be told I should raise the turn. Any worries about the flush? In retrospect, Villain bet/calling the flop and then leading the turn seems more like a pair with a single spade to me than a made flush. At any rate, this is my biggest question -- how do I play the turn and why?

Thanks.
