Exterior care is really going to be dependent on your local environment and how they're stored. If you're in a more humid environment they'll need more frequent attention to keep them from rusting, whereas in an arid environment you can get away with less frequent attention. Whether they're stored in a climate controlled area or not will also make a difference.
As for bore maintenance, 100 rounds/month is nothing for a rimfire. Personally I would just run an oiled patch down each bore, followed by a dry patch or two after each training session. Then maybe every 4-6 months give the bore a good thorough cleaning with solvent.
