Sounds like you are doing more than you need to, which is good.
1) Masts can be left outside, track facing down. I have had ice blowout a mast track on a mast that was left up for the winter. Dry storage for the mast is even better, especially if you have a comp tip as it gets it out of the sun.
2) Remove battens if you plan to fold your sails. Otherwise just release tension from the battens. The biggest risk with sails over the winter is mice. Whatever method protects the sails from mice is the best method. Fold sails like this:

4) With all the work you are doing on the masts, boom, sails and rudders it only makes sense to pull the tramps. Snow buildup can strain the tramps and keeping them indoors reduces UV damage.
In order of importance: Sails, tramps, spars and rudders.
Placed on tires in a driveway is a very nice place, so long as your snowthrower/plow doesn't put it at risk. Once my boats are ready for winter I just put them out to pasture on their trailers.
