how much would a nut replacement cost? not the material, but if i got a blank graph tech tusq nut (~$5) how much would it cost to get the old nut pulled off, and the new one shaped and installed on an Ibanez RGA121?

Depends on where you take it, but likely around $20-ish.

Thanks for the quick reply, do you know what is actually done when the nut is replaced, the procedure?
Well assuming the setup on your guitar is currently alright, all the tech has to do is cut the slots so that the strings in them properly and don't cause too much tension at the first fret. It isn't a really complex procedure, but there are little things you need to do when shaping the slots to make sure that the strings don't get muffled or bind up and cause tuning problems.
