Red-B, thanks. If it gets to that, I'll let you know. I don't know about charging AC, but how hard could it be, especially with the help of the board and the Internet.
Regarding finding the leak. I'd find the leak, and then if it was something like a Schader valve, that would, presumably, be an easy fix. I assume I'd have to let the system leak down to nothing before I could "repair" any issues, though.

You could pump the unit down which just requires you to close the valve on the discharge line, leave the suction line open, manually depress the contactor with a GOOD INSULATED screwdriver, and pull all the refrigerant back into the system through the suction line. Then you close the suction line. The bigger issue would be needing a vacuum pump and gauges to put the system into a vacuum after repairing the schrader valve.
As far as charging goes, gauges and a tank of refrigerant. Add refrigerant slowly until you see the suction line start to sweat on the outdoor unit. Once you've got condensation on the suction line, you're "good enough"
