Against a player like this - live fish player - i think you have to re-raise the flop, you are getting paid by all the worse draws, and have decent equity to made hands range 77+, sets or the rare case of flopped straight.
About the turn play, in my experience against this kind of fish, is never a bluf, he may have 5x type of hand or betting 77+ for value.

First of all you have to feel comfortable with the game you are playing in, meaning that you are ready to face a swing of a couple of buy-ins, without feeling comfortable with this there is nothing you can do against such a player. Probably he is completely aware of your situation (taking shots). The next question is why you want to play this game? To exploit the lag from your description or to exploit other spots at the table?
