simply keep your saved game folder. If you've created any items yourself (using IEEP), then copy those over from your override folder and paste them back in after the re-install. If you've enabled cheats, then after you install, you have to re-enter the cheat line into your baldur.ini file. Do not keep the baldur.ini file however; if you do, the full install will not take effect. You know those movies that you see sometimes when you enter an area? You'll end up seeing them again, although that is not a big deal at all. Other then that, just do a full re-install and you're good to go.
