I am sure there is a special tool to perform this task but I just use a wrench on the idler nut to release the tension on the belt. It really helps to have 3 hands tho. If you don't have a schematic under the hood showing the correct routing of the belt, be sure you draw one up yourself so there is no question as to how it came off.

It is always a good idea to replace the belt as soon as you see anything like this. Believe me. I work in a parts store and you don't know how many times I get the torn remians of a belt thrown at me by a customer who said he/she saw the belt's condition but figured it could wait. As far as the tools and labor, serpentine's are fairly easy. There is a tool that is basically a long skinny socket wrench made to fit in the tight space, but it isn't necessary, just convenient. You can find it in almost any car parts store. Just be sure to run the belt correctly around the pulleys. One more thing, DON'T SKIMP ON THE BELTS! The El Cheapo brand is called that for a reason and broken down on the side of the road is not a good place to figure this out. From what I've seen, the Dayco brand is a great and reliable brand.
I'd like to offer a bit of advice if I could. either get two new belts or keep the old one behind the seat for a spare. It might be worn, but if you have a belt break unexpectedly, the old one will at least get you to a parts store.

I've had great peformance and luck with Goodyear's Gatorback belt. They're quiet and have a lifetime warranty. On my 90, I use a 5/8" socket and a breaker bar, takes about 60 seconds if you know the routing.
Ever notice the warnings on those sleeves? "Warning, Turn off engine before replacing belt"...
