Welcome to the club! As far as storage is concerned, it'* the worst thing you can do. Trust me. Mine was stored for 5 years before I bought it. Rust will wreak havoc on your exhaust. Your catalytic converter and muffler, especially (the internals) but don't worry about the piping. It'* all mandrel-bent stainless steel.
Do plugs and wires, O2 sensor, fuel filter, air filter, pcv valve, etc. Do this asap. Pretty cheap too, but well worth your time. You'll likely have a few little electrical bugs for a short period of time.
Enjoy the ride!
