I would keep the stock setup sort of. New hoses is a good idea as is eliminating the suction throttling valve. If you want a Sanden compressor, that will work too. Kepping the expansion valve or going to an expansion tube is up to you. But the OEM air handling system is the best. Outside air is used for heating and you can re-circulate the air for max cooling.

All of the aftermarket HVAC systems only recirculate the air, so during heat mode, the windshiel can fog. BUT you live in Cali. Your "cold" front is what 40° F? Mine is 0° F, so the issue is much bigger for me.
