you may be able to syphon the tank instead of dropping it, then add some Stabil to cut the little bit left behind. Then, fill it at least 1/2 way to thin out any little bit of old gas left in there. Three years is not to bad for gas, it will have a slight laquer smell but should still burn ok. If it smells really really bad, re-visit the three year thing. May have been sitting longer...
Also, check your air cleaner system and exhaust for nests from bugs or rodents. Your plug wires might still be ok, just check them for dry-rot by bending them. If there are cracks, replace 'em, if not, use 'em.
When you first drive it, take it slow. Oil needs to get back into the seals on the engine, trans and rear end. If you pull out of the garage and nail it, your bound to get something leaking. Baby it for a few days to let them all soften up again.
I picked up a chevy van that sat for 12 years, only had 14,600 miles on it. The tires where peeling off the tread, lots of cracked up rubber. But I tell ya, I drove two hours to get it with a battery and a tool box. Put in the new battery, checked the oil, fired it right up and drove 1 mile to discount tire for new ones. Filled up the tank with fresh gas to cut the old stuff, then drove it two hours home. Once home, I replaced a ton of stuff. Wires, plugs, etc... Six months later I drove it to Montana from Michigan (a 32 hr. each way trip, twice!) On the second trip, I lost my water pump. It started leaking out the front shaft, fortunatley we heard it at a rest stop and shut her down before running out and overheating. At that time, I replaced all the hoses as well... Then, I noticed a drag and a funny air sound when passing, you got it, my Catalitic convertors were shot! I then spent $370 and had all new exhaust put on from the manifolds back. I still drive the van, repainted the hole thing with a dark metallic blue. It currently has 61,000 original miles. (its a 1986) Oh, can't forget... we did the rear brakes just before the second trip to Montana. While apart, we pulled the axles, cleaned and re-filled the rear end and replaced the seals as one side was starting to leak.
If you want to spend the money, all the new stuff will not hurt matters any but personally, I don't think three years is long at all for sitting. Should'nt be near the amount of work as you are thinking. I would throw in a battery and try to fire her up in my opinion. First stop would be a full tank of high octane to help clean 'er out a bit.
