Put some seafoam in the tank and put it on some jack stands. Close your windows and I would put a rag in the tail pipe to stop misture and creatures from going in there.
Also if its going to be in the sun try and cover it. Or put small tarps over the hood, roof, hatch and cover your dash with a beach towel.
No matter what, start the car every 2 weeks to clean out the injectors from gumming up.
If you have a bettery tender then take out the cell and keep it on a 1amp charge or 1/2 amp charge for the time you're going to be storing it.
Never keep the battery on the ground, they say the earth draws out power.
You should be ready to store it..
