No point in not replacing the compressor just to find out that you need a compressor and have to pay to get the refrigerant recovered, do the repair, and then vacuumed/charge the system. That's just extra money down the drain. Your system held pressure before puncturing the condenser so that would lead me to believe your compressor has failed.

The 30 minute vacuum test was recommended in the Toyota Service Manual so I think there is a reason for it.....especially after all new components are installed.....IMO
