No need for flushing, IMO.  That's for when you've had a compressor failure that dumped garbage in the system, or have too much oil or something.

If you do flush, don't flush through either the receiver/dryer or the expansion valve.  Disconnect the evaporator and condenser and flush them independently.  And unless you flush with refrigerant, be darn sure to get all of the solvent back out.
