Its not terribly difficult if you can read, understand, read, understand and repeat. Then you have to have the patience to do it right. Many people will tell you that you simply cannot learn to do gears by reading and/or by having someone show you. This is partly true as I learned how to do gears via lots of reading and asking a few questions on here (thanks again readymix). There is no in between with gears, they are either pretty much right or they are incorrectly setup. For a "novice" you certainly should consider a shop doing it to be certain they are right. There are also a few speciality type tools you need to do the install properly. It is time consuming and takes patience but it is quite rewarding to do yourself. Let us know if you have questions if you do undertake it yourself, its not an easy task but is fun to do.
