So we handled the Secretary of State just about perfectly. We'd gone in with plenty of documentation, had to head back briefly, but, we achieved the goals of getting my temporary Michigan driver's license, got my car insurance changed over, got new car registration, and got new plates, and for all that we took maybe two hours start to stop. (It helped that there was an office in the mall not two miles from our home.)
So we went to putting the new plates on. Well, the new plate, since Michigan only has rear plates, which is one of many parts of Michigan automobile-related laws that strike me as signs of rampant immorality. (They also don't have auto inspections; I can barely stand that New Jersey dropped to biennial car inspections.) But while 
bunny_hugger found the screwdriver of the right size to take the old plates off, I put the registration sticker --- something New Jersey does not have, at least not since biennial inspections went in --- on the plate where it would turn out to be partially obscured by the dealer's plate frame. Well, no police have bothered me about it yet.
bunny_hugger discovered that for the front plates my dealer originally had not been fitted into the properly moulded spots on the bumper. Actually, the front bumper made no allowance for license plates; my car had no provision for front plates. There were just holes drilled right into the fiberglass. After cleaning the bumper I decided the least unattractive thing to do with the holes was replace the dealer's plate frame. I haven't found anything to take the plate's place, but at least there's not the open holes dangling loose in the breeze.
A couple weeks later Michigan sent my actual non-temporary driver's license, so I didn't have to go driving with the sheet of paper stapled to my New Jersey license, something I managed to leave the house a few times without anyway. They also sent a voter ID card, which was kind, but they needn't have bothered. Surely the polling place's workers will notice I'm a white male.
