Also, I would highly recommend buying a copy of <a href="http://www.amazon.com/Linux-Dummies-7th-Dee-Ann-LeBlanc/dp/0471752827/sr=8-1/qid=1159823656/ref=pd_bbs_1/102-2179383-6991301?ie=UTF8&s=books"><i>Linux for Dummies</i></a>. When I put Linux on one of my computers, I found it a very good tutorial for learning how to use and get around Linux. The other reason I liked it is that it showed you how to do things from the command line so that you won't have to rely on a GUI to get things done.

It's also nice because it comes with a DVD of a couple of different Linux distributions on it.
