Hi Bikenut.
I have the very same bike and in the same situation, I was using the bike for work but when I changed jobs I stored it in my fathers garage(in my case 30years).
I wanted to now start cycling for fun albeit not long journeys.
Anyway I got the bike back and found a lot of it was rusted up, i.e. rust on the rear wheel gear set, the wheel rims are pitted, the brake calipers are near solid and rust showing on the chrome and a bit of rust on the main frame although very, very little and after cleaning with metal polish just has a few bubbles on the paint work.
Oh and the tyres are perished.
I was in the process of buying a hybrid bike but seeing this thread and your original post wondered if I could get mine working again.
Please could you give me tips on how I would go about it if possible to get mine back in working order.
