I like to change oil in the spring if it is stored in an unheated garage. Some condensation may build up in the crankcase over the winter and will be there until the engine is fully warmed up.
That is also why it is better to store with a full tank of fuel to reduce condensation and rust.
I guess you could also crack the oil drain in the spring and drain any moisture out then
As for running the carb dry. Install a shutoff valve before the fuel pump. Shut it off in the fall, unhook the suction line so the pump does not have solid dry line. Then start and run the engine until the carb runs dry.
You could also "fog the engine" when it starts to sputter to coat the cylinder walls. Here an article.

Set the truck or car up on blocks the let the suspension rest for a few months.
I'm sure there is more you can do, depending on the time period it will be stored and your conditions.

More people will be jumping in here to give their thoughts on do's and don'ts.
