If you replace the compressor yourself, you'll still have to take it to a shop to get it evacuated and recharged. The auto supply won't sell refrigerant to anyone except a licensed AC technician due to environmental laws. I used to do some of my own AC work, but can't legally get the refrigerant any more. Replace the dryer while you're at it and the take it somewhere for the charge. Tell them what you did so they'll put an oil charge in as well.
