Provided you know the difference between a 1/2 inch socket and a 3/4 inch socket, you outta be able to get a good handle on it in a months time.
Lots of good advice so far, but i'd like to stress what Brian McGee said.. if the truck has been sitting for 19+ years, the very first thing you're going to wanna do is make sure that the engine isnt stuck!
A bent or busted crank isn't going to be something you wanna start out trying to fix!
With the sparkplugs removed (pay close attention to where the wires go so you can put it back together again!) spray a generous amount of WD40 or other penetrating oil down the "holes".
Then with the transmission in neutral, try and turn the engine over by hand by the fan. With no sparkplugs in the engine, this outta be pretty easy to do. If she won't turn, or you really have to struggle to get it to turn over, then spray some more penetrating oil down the sparkplug holes and let it sit and soak.
While it's soaking, this is also a good time to drain the old gas out of the fuel tank, and pull the valve cover off and spray the crap out of the rocker arms, valve springs, and other associated moving things.
Once everything is all lubed up and moving freely, put a fresh set of spark plugs in (new wires, cap, rotor won't hurt, either!) put a fresh battery in along with fresh, new battery cables and fire it up!
If she won't start from there, we'll probably need to know what engine you have in it before giving specific advice (i.e. is it original motor, or did somebody put a 350 in there?)
