Combo hand, TPGK + Flush Draw against a maniac question.

[jman220]

Did I misplay this preflop or flop? Villain is a Super-lagarific maniac. out of the last 25 hands or so he has gone all in for $100 into $2 pots preflop. He overbets every pot. He's something like VP$IP 83, PFR% 45ish. I have about 70 hands on him at the time.
