You're referring to the Chilton's and Haynes' manuals. They are ok for very basic stuff like brakes but beyond that, they are not a good choice. The reason being that those types of manuals attempt to cover too many model years so they aren't all that accurate on any of them.
If you plan to do your own work, even if it doesn't include engine or transmission overhauls, I strongly recommend the Mopar Jeep Factory Service Manual. They are made for each specific model year and are well worth the $$$. You can find them on eBay or at your dealership. There are CD-ROM or DVD versions that are fairly inexpensive but I personally like the printed version so I can thumb through it while I'm actually working in the garage.
