In your shoes I'd see about getting the wheels off of the ground, but probably without totally unloading the suspension. So, cheap jackstands placed on the suspension right inside of the wheels if possible. Cover the wheels to reduce the likelihood of the sun damaging the tires. I'm unsure if you should somewhat depressurize the tires from full pressure or not. Obviously you don't want to break the bead, and you don't want to have pressure lead to cracking.
Cardboard cut to fit in the windows snugly would be helpful to protect the interior. A car cover would be better, but you'd need to take it off from time to time to clean both it and the car.
Give it an oil change with synthetic right before starting it to move it to its storage place.
If there are any grease fittings on the suspension, lube them and wipe off the excess.
My Stratus had a drain plug on the fuel tank, you might want to see if you can drain out the fuel tank.
If you have a fixed-mast antenna, take it off and store it inside the car so that it doesn't get damaged.
Unhook the battery, possibly remove it from the vehicle entirely. If there are any radio security reset codes, be sure that you know where they are in advance.
Put a checklist on the driver's seat for when you want to put it back on the road again for any other fluids that you may choose to drain, and to check all levels and the belts and hoses and tire pressure and the like. Also, if it sits a particularly long time, consider changing out the brake fluid and coolant when putting it back into service. It's also possible that the liftgate hydraulics could have problems, be careful with that.
