Pontiac Repair: 2001 Grand Prix A/C Condenser, condenser, right tools

Question
It's been determined that the A/C condenser in my 2001 Grand Prix needs to be replaced.  Any advice on how to go about doing this?  There's also a possibility of the compressor also having to be replaced.

Answer
when  you start messing with the a/c system it requires specail tools and pumps i suugest you go without a/c until you can have a shop do it  with the right tools, you can save some money if you buy some used parts if the shop will work with you on them
