Title does not need to be in his name. Check with your insurance agent re: the insurance, he may need a separate policy since he will be a resident of a different state.
As a Florida resident, he'll need to get a FL DL - we have "Real ID" so original birth cert (they wouldn't take my certified copy, made me pay $15 to get a new one at that desk over there, use your current certified copy to prove it is you), proof of social, and several proofs of address (utility bill, etc)
Good news is that a CCW permit is easy - just can't carry on college campuses
