Maniac on flush draw, hows my line?

[Acehawk74]

Playing against an absolute maniac. Only 10 hands on the guy, but he was 100/90, and I had seen him do the following:

Min-raise every flop not raised to him
Showdown some abysmal hands after calling them down, getting lucky, etc..

I put him on a flush draw on the flop.. and I'm not sure about how I played this. I am new to NL cash games (came from SNGs), and this is at NL 25. The end of the hand made me laugh.

I look forward to your comments.
