AC Condensor 300SD - how much oil to add?

Hello,

I've got a leaking AC Condensor (Front Right part from the metal tubing)- looks like a pinhole leak. This is the original condensor.

THis is R-134 retrofitted system. For 9-10 years now, it's been running well with occasional addition of oil and refrigerant to top it up. At the time the receiverdryer, expansion valve, compressor and manifold were changed and flushed with brake fluid (done by a mechanic friend).

Question:
1. how easily is the condensor removed (i've removed the coolant radiator easily in the past).
2. once replaced with a new one, any pitfalls? How much PAG should I add to compensate for the loss?
3. will replace Receiver-Dryer along with the pressure switches.
4. I'm NOT planning changing any of the system hoses at this time. (AC Manifold hose replaced 10 y ago). The hose from condensor to the receiver dryer looks cheap though.

I will have the system evacuated and recharged by an AC Shop locally taht did the charge for me last time. Any precautions or advise? I thnk the aux fan may have been the problem, as its locked up and will need to be replaced as well. (will order).

Can average AC Shops do a good aftermarket replacement of the condensor rather than buying one from fastlane...since I'm going there anyway to have the system charged? or is there any advantage to having a german one from fastlane? I'm not sure what types of parts they would use?
