Yup, what he said, get that oil changed, get some fresh gas in it. If you don't have any diesel, spray some WD-40 down the cylinders and let it sit for a few minutes, this will help loosen up anything that might be stuck and help your rings to re-seal. After sitting some of the engine gaskets may have dried out, but you won't know until you fire it.

Same with the brakes, after sitting you may have some of the rubber drying out. Check the system real good before you get it on the road and get some good brake fluid in it. Make sure your wheel cylinders and calipers don't leak. Inspect the rubber parts real well too, hoses and the master cylinder for leakage. You will sometimes see these parts fail after sitting, so work them before you drive it off and work them good, make sure you bleed them and work that pedal. Get some good gas in the carb before you fire it, this will help burn out the crappy stuff in the lines and what not. Good luck.
