I'd like to offer some other thoughts:

1) COMPLETELY drain the fuel system. Then mix up a small amount of oil/gas and pump it through the system to leave a lubricating coat on fuel pump and regulator. Rubber will dry out in pumps and regulators

2) Jack stands - good idea, but you need to put some support under the suspension. The idea is not to let the suspension be completely loaded (as normal) or fully unloaded - just support the suspension.

3) Disconnect the battery

4) Completely drain the radiator and block. don't use antifreeze. If everything is dry, the cold won't split anything on you.

5) If the car is really going to sit unused for an extended period of time, I suggest removing the tires/wheels and stacking them in a place where they aren't exposed to direct sunlight. Put them on a piece of plywood or cardboard - not directly on the garage floor. I wipe with Armor-All before storing would be a good idea too.

6) Definitely back off the rocker arms and lubricate the cylinders.

7) If time in your schedule allows, go out and reverse this process once a year and start the car up and run it - even on jack stands.
