When re-routed to bypass the AC compressor, some of the contact area for the belt on the water pump pulley is lost, but as long as the pump turns without slipping, there should be no troubles. If the belt slips on the WP pulley, you should hear a squeal.
The AC delete pulley is a good fix, though. And for $35, that'* not a whole lot more than a good belt anyway. Glad you got it fixed.
Re venting: Unscrew a cap on an AC line and depress the schrader valve for an instant - just long enough to see if there is residual refrigerant in the system. If it hisses strongly, take it to an AC shop and ask them if they will pump out the R-12 for the value of the refrigerant. Most shops will do this for you.
