One of my 4 main guitars is an 89 RG560. You should be able to get it up to spec no problem (a cracked neck isnt really a big deal - it'll be the strongest part of the neck after its glued).
The Edge on mine is as stable as any OFR, schaller or gotoh I've used, and its the original trem. Check it over, but I wouldnt expect any problem with it (unless its been divebombed to hell and back for 20 years).
Have a look inside the neck join for cracks in the heel too; a common problem with old RGs.
