Do I have to generate a new Final gather map and/or Photon map when I move, add, or modify any lights or geometry? Or can I just overwrite the current existing map?

note: I'm running max 2010

You need to delete the file and recreate it. mr will not replace any points that already have been calculated, and you will end up with a splotchy rendering otherwise.
