Got to do mine in a couple of weeks when I get back from holiday - curious about this myself. I think it's a good idea to go ahead and do the dryer at the same time if it's not been done and to get the whole thing deep vacuumed before replacing the refrigerant to get any water out of the system that might otherwise turn to acid over time and ruin your new condensor. Sadly, this is all I know of the job - I've not seen any photos or walkthroughs of the process beyond what is in the RAVE.
