Answer 1

Can't give you an answer only knowing the brand of the bike itself.....we need to know what kind of shifter you're working with.  It's an easy job to do, although you'll have to learn how to adjust the rear derailleur as well....it's part of the process.  

Post up again with more info, or if you want you can visit the "repair help" section at http://www.parktool.com .  It has excellent instructions and photos to teach you about nearly all bike maintenance jobs.  Probably one of the neatest cycling-related things to appear on the internet....seriously.

Just be careful not to break the shifter
