One thing you'll want to do is to replace both the cam and crank sprockets along with the chain. Everything wears together as a set, and thus should be replaced as a set. You'll need a puller to get the crankshaft sprocket off.
The sprockets have timing marks and are keyed to go onto their respective shafts only one way (just make sure they aren't flipped), so once you get the cover off you'll want to turn the engine by hand until the timing marks line up, and then leave it there as you remove the old chain/sprockets and install the new ones. Once the new ones are in place, check to be sure the marks still line up and then turn the engine by hand through one full revolution, checking again to be sure the marks stay lined up. If all is well, close everything up and start 'er up. It's not a bad idea to change the oil soon after you do this.
I recently did this same job on my '96 S-10 2.2L, and it really wasn't as bad as I thought it would be. The toughest part was prying the timing cover out and fitting it back into place; chain and sprocket removal was pretty easy.
