I have stored car before and here are my recommendations.
* Put the vehicle on jack stands. Parking it for a years will leave flat spots, even at max PSI. I wouldn't worry about the suspension.
* Fresh oil change is a must.
* Fill the gas tank up completely to prevent condensation.
* Gas treatment (put it in before you fill up and drive it to it's home)
* Take battery out and put it on a tender. You will be buying a new one if you don't.
* Depending on where you park it, it will get incredibly dirty. Car cover or a good waxing is not a bad idea if you care about your paint. Especially if you park it near a tree with sap.
* Sun shade. Believe it or not, but sun hitting the same side of the car every day can cause unusual bleaching / shrinking of the interior.
* Steel wool in the intake/muffler isn't a bad idea, but remember to take it out.
* When you park it think about everything from storms, rain, overhanging trees, rodents, ect.
* Make sure someone has the keys for an emergency.
I would recommend misting the cylinders with oil when you get back and before you start it. One of my cars wasn't burning any oil at all until it was parked. (Sticking ring or something, I don't know.)
