most body shops or damage repair / paint shops should be able to do the stone chipping and keep it localised without the need for respraying, if done right the touch up kits csan be effected but I'd use the technique in the 2nd post link to achieve a good finish.
Mine's in for damae repair atm and I asked them to do the chips whilst it was in, they said it wasn't a
problem at all to do, nothing of a job for the pros
