If the compressor failed "catastrophically" (which I would say means cracked) then you must flush the entire system and possibly replace other components. Additionally if outside air has entered the system the oil will become acidic and corrode components and the dessicant will swell and potentially burst the bag in the drier causing more problems.
Any time the system is opened it must be evacuated in order to boil off any moisture. After a compressor replacement you should add the correct amount of PAG oil back into the system. You need a manifold set to get the pressures on the high and low side, but I'd guess you've either got too much oil in the system or undercharged with refrigerant. You could also have an orifice tube plug with compressor debris.
