If its only surface rust dont worry about it. Fix the leak and dont worry about it.
If it makes you feel better to get rid of it now, sand it off and treat the metal with Metal Prep or Picklex 20 or Ospho or some other form of metal prep. I like the Picklex personally but there are plenty of others that work fine for what you need right now.
