I'm pretty sure the current hoses just need these type of fittings to connect to the new compressor. Or are the old and new compressors so different the new one, Sanden 508 style, will not work with my R-134a system?

You are correct, that's the POA valve. It needs calibrating before the system is charged. F.A.A.Benny on this forum can do it (I have not used him but many here have)
The fittings in your picture will work, they have the correct R134a service ports
the Sanden 508 compressor is designed for R134a (Sanden has discontinued making R12 compressors)
