This handy little truck is not an easy one to change the plugs on. Do yourself a favor, buy platinum plugs. If the engine is reasonably sound, platinums will last over 100,000 miles.
First collect the following tools. 1) A Good quality 3/8" flex head ratchet. 2) A good thin wall 5/8" spark plug socket. (the clearance between spark plug and side of the cylinder head is small, making thin wall a necessity) 3) a good collection of extensions for the ratchet. Here is a place where you can use cheaper extensions. You should have a 1.5, 3, and 6" extensions. 4) A 3/8" universal joint. 5) A short socket that is the same size as the closed end of the spark plug socket. This is usually 3/4".
With this collection, you should be able to change the plugs. With the inside engine cover off I think you can reach all the plugs from above. If you have to use the universal joint, you need to hold both the handle of the ratchet and the other end of it. If not the ratchet will just twist out of the way.
One trick for you. Get yourself a section of 3/8" id rubber hose. Put the porcelain end of the new spark plug into one end of the hose. This will allow you to start the plugs much easier. A little anti seize on the threads will help them come out easier next time. Lots of patience needed here. Important note, only one plug wire off at a time. Twist the plug wire to get it loose before trying to pull it off. Good luck. Go slow.
as Bob C said with a selection of various tools. The way to approach is to get as many plugs out from under the hood. Then there are some you can geet through the wheel well and the back ones can come out from the bottom. It easy if you have access to a lift. good luck!
