When storing my 107 in my garage each winter (Nov-April), I put a tender on the battery. Obviously, the summers in Fla are not like the winters in NY, but the tender prevents any worries. Otherwise, I would disconnect the positive.
-Change the oil and check tires as you mentioned
-Clean the car thoroughly inside and out
-Fill the car with gas and treat the gas with Stab-Bil or similar just before driving it to storage.
-Place dryer sheets strategically throughout the interior, trunk, and engine compartment to help ward off rodent infestation. (some others prefer mothballs, but I don't like the smell and believe dryer sheets work as well)
-For added insurance, I place mouse traps next to each wheel to ward off climbing onto/into vehicle.
-Crack the front windows ever so slightly for ventilation
-Put a car cover or dust cover (eg: sheet) on it
