The wheel has already been re-built by the LBS, TREK will tell him that their obligation is done. He needs to go back to the LBS. 32 spokes should be fine for his weight, 36 would be better, but 32 spoke wheel should not be breaking spokes unless the LBS is re-using a out of round wheel and varying tension to get a true wheel.
OP, is there any way for you to check tension on the spokes? Sometimes you can tell there is tension difference by squeezing them together even if you can't tell how much tension there is.
