I think you have a good plan. I hope your car has been in a garage all this time. Being outdoors is tough on a car that's idle. The best thing for an engine that's been sitting for a while is to run it! As long as it starts up and goes, the next items to check out are transmission function, cooling system, and brakes.
Storage is tougher on brakes than on the engine.
