The oil thing is an old wives' tale. I switched mine ('05 model) back to dino oil (Rotella) and have had no issues. Too bad he didn't run in some Stabil to the tank before winter.
I'd probably flush the brake fluid on both resevoirs, check the clutch for ease of use (might have to lube the cable). Check the brake pads to make sure there's some pad left on both ends. Check tires for proper inflation level, change oil and filter, and turn it over to make sure she runs alright. Once you get it running, run through the remaining gas and refill the tank and run that too in less than a few days. The fresh fuel should help flush out some of the settled residue from the untreated fuel. Wash and wax the thing thoroughly.
I'd probably avoid using any of those fuel system cleaners unless you really have engine issues.
EDIT: Get a service manual if you plan to do any of the service work yourself. You might be approaching the period when checking valve clearance is required.
