On the X360 you don't have to delete the character save's as the game and save file's are separate. I'm not sure regarding the PS3, you can at least backup character save's to a usb drive. If you re-install and try a new character briefly to check for the bug, as this may narrow it down to a bug or the disc. You may lose unique item's from the add-on's if your character's have done any Dragonborn or Dawnguard quest's.
