also get a reciever drier for the system as well. when your compressor goes out obviously it sends little pieces of metal and crap into your system. even tho the reciever drier isnt ment to be a filter really, it catches that crap and it stays in there so your system is clogged, your high and low side pressures will be off, therfore wont cool as good as it should. if you take it up to a shop, tell them that oil needs to be put into it. (even tho that should be obvious.) The oil doesnt stay in the compressor, it flowes through the entire system. i would recomend short belting the system and just having a shop do it just because they have the proper tools to take care of it.
