A bolt is a threaded shaft with a head to provide a place to tighten. A
stud is a bolt without a head.
You should not put anti-seize on the studs.

If the lug nuts are only finger-tight or snug, the wheel may not be seated
properly. The Camry's manual assumes that the owner is smart enough to make
sure that the wheel is properly seated before lowering.

I'm in So Cal so I don't worry about rust much, but if I was in the
snow belt I'd give the hubs and the back side of steel wheels a quick
shot of High Heat Barbecue Paint when new, and whenever worked on, to
keep the wheels from rusting to the hubs.
You don't put on thick paint that could make the rim sit on the hub
cockeyed. The paint is going to wear through at the clamping contact
points eventually, you want to keep the /other/ areas from rusting.

Why do you only tighten the lug nuts finger-tight while the car is in
the air, and wait until it is lowered to tighten them to their final
torque? I always tighten them to their final torques (in a star
pattern) while the car is in the air, and I know that when the car is on
the lift at the service centre, they do the same.

If the wheel is not in contact with the ground, tightening the lug nuts with
a wrench just spins the entire wheel. if you have an impact gun, this is
not a problem.

Toyota assumed that soccer moms would be smart enough to change their
oil....and sludge happened....
