I'd say there's really no need for a 36 spoke wheel. I'm just a skosh under 200 lbs myself and all my present fleet has 32 spoke wheels that are doing just fine. Even the heavy load shopping bike, which is the one with the set of wheels I mentioned above, is 32 spoke'd and has been totally trouble free despite a fairly routine life of rough roads and 20 or more lbs of junk in the saddlebags.

For longer range loaded touring I'd like the extra insurance of 36 spokes but for the OP I seriously doubt he needs anything more than a nicely tuned up 32 spoke wheelset.
