Yep. Don't store a dirty car!! Clean the car well, including the wheel wells, trunks and behind the rocker panels (where dirt accumulates, stores water and rusts).
Done
Pull the battery out entirely. It'll only take 5 minutes, and then you won't wonder. Still do your baking soda routine.
Done
Clean the interior, focusing on any crumbs or spilled drinks (think - cold and hungry rodent smells something good and comes to chew up your interior.)
What.... crumbs in my car?...I don't think so, I don't let the kids eat in it.
Mothball the hell out of the inside and the engine compartment.
Does this keep the rust moths from the hell hole?
Some window screen material over the air intake and the exhaust. Wire it down with twist-ties, and you can see if any little critters have chewed their way in.
Good idea, never have needed that up here as we don't really have many rodents. (I don't think they will make it past the oil bath anyway
)
Put down plastic sheeting under the car, to prevent moisture from going UP into your car. Yes, especially if it's a concrete slab.
Never heard of that one before either. With the winters running mostly about 10-30% humidity the air is pretty dry.
Lubricate all your seals (door, window, targa, etc) with some glycerine.

You can put the car on jackstands, and pull the tires. That should help them from becoming flat-spotted.
Done
that's all I can think of right now. Hope this helps!
It did, if nothing else it gave me peace of mind to know I did as much as I could for this year.
BTW - for the 14th year in a row, the guy with the Z28 next to my car, ran it though the local car wash, backed it in the garage, took out the key and walked away. His car is still in mint condition.
