A/C Compressor Pulley?

While driving one day our hood started smoking. We pulled over at the next parking lot to assess the damage. As we waited for the smoke to clear we heard a telltale thunk from the belt tensioner pulley. Our serpentine belt had snapped. Our friend helped us replace the belt, but it melted and snapped three days later. Upon further inspection it became clear that the ac compressor pulley was wobbling, the plate covering it rusty and its rubber bits almost crumbled. We replaced the belt again with the help of another certified friend, at which point it started up, so we shut the engine off. Then we tried to turn the engine on later and there was a deep grinding and it refused to turn over. The pulley is now pretty jammed up.

Do I: a) buy a new pulley for the ac compressor
b) buy a pulley bypass (if so which one)
c) remove the pulley and try to fix it (if so, how?)
d) buy a whole new ac compressor

Also, how do I know if there is refrigerant to be drained from the compressor and is there a way to do it from a parking lot with a ratchet set and serpentine belt tensioner bar? Step-by-step instructions would be greatly appreciated.
I am looking for the lowest cost option in order to continue working to make it to tax time.
