It is a little hard for someone to dive right into Linux if all they know is Windows. If you have a local Technical College in your area, check to see if they teach a class on it. Mine teaches a Introduction class and an Advanced class.
If you want to continue to try Linux, download one of the newer versions from
http://www.linuxiso.org. Red Hat 7 is kind of old now. But in its defense, version 7.2 was pretty damn good. You may want to start with Mandrake. People tell me that is the easiest to learn on.
