Ask people that winterize boats. They do lots every year in the worst possible conditions.
After you're done, do not start the car until you're ready to drive in the spring. Running a car in the driveway will not heat the oil up enough to get the moisture out. Water temp might hit 190, but the oil takes some driving to heat it up. Idling will create more moisture in the crankcase, which is worse than not starting it at all. I've seen bearing lower halfs with "water marks" where corrosive combustion products eat into them.
Idling it also wont heat up the entire exhaust enough, so you'll have more corrosion in there.
So...
Check your antifreeze, tire pressures, etc
Add some Stabil to the tank and run it enough to get to the carb.
Change the oil.
Grease all the fittings.
Spray fogging oil in the carb until it kills the motor. Or disconnect the coil and spray while cranking.
I leave the battery in with an automatic charger.
Leave it til spring.
