I'll disconnect my ground cable from the battery, put a cover on it and put it on my lift.
You can add some PSI to the tires to avoid flat spots or put it up on jack stands.
I don't think parking it outside would matter as long as it's covered.
I've seen dryer sheets or bars of soap placed in the cockpit to ward off critters.
Maybe consider a canopy over the car even if it is covered as snow/ice may settle in the cockpit despite a cover.
Make sure your antifreeze is mixed appropriately for the anticipated temps.

 

My winter storage procedure with mine:
1) Pull into the garage
2) Shut off the engine and remove the key
3) Close the door and turn off the light

In the spring reverse the process. Worked flawlessly for 17 winters.

Normally I agree with Jeff, but in your case, you should get it a set of nice warm mittens and some hot chocolate

 

I got a nice winter coat, gloves and a hat and keep driving.

 

I'm a cold weather wuss...anything below 45° is too cold for me...and that was once to the last car show of the season.

 

I'm with Jeff. I bought an inclosed 20 ft car trailer to keep mine in. Its ready to go any time at the drop of a hat. Conn isnt known for its warm winter weather but I've taken it for a ride on an odd warmish dry winter day occasionally over the years.

 

I have a drive in basement garage, it never gets below 65 down there if I don't put it on jack stands it takes five miles for the tires to round out

 

I have three "toys" (FFR Type 65, Triumph Spitfire and Opel GT). They are all garaged and I try to start them up and let them run to temperature at least once per month through the winter. I'm do not always meet this schedule, but so far (20+ years) I have not had any difficulties. I do put rhodent repellent packs into the dark places -- under hood, under seata, in the trunk -- emphasis on "repellent" and not poison that might attract them,
