1) don't know too muchg about the gunsite safety, but recall it coming up occasionally on Parts & gunsmithing forum, try there if you don't ge any answer's here.
2> Bomar makes some night sights IIRC, if you're still wanting adjustable sights. Since Colt actually uses Bomar's instead of just copying them, you should be able to get an interchangeable one. If not, try Heinie or Wilson Combat.
3> the Memory groove will require frame modification, gunsmith fitting recommended. You can get a drop in King's grip safety for a commander and it will fit nicely enough.
4> Not sure, probably depends on your area for price. The Gold Cup's have a unique hammer/ sear. While you can put in a new set without problem, the original parts are pretty neat too
