Well, Red Hat 9.0 is pretty old (March 31, 2003) and linux distros are quite a bit easier nowadays. If you like the Red Hat distributions, try Fedora or CentOS. If you want to try something else, go to distrowatch and download one of the top 10 distros. Sorry, if you don't know, distros are "flavors" of linux. Each one usually contains a selected set of programs all bundled together to suit the creators' need. Other programs can be added and each distro handles things like program installation slightly differently.
The biggest thing to know is that Linux is NOT Windows. You'll have to unlearn some things. You can start by visiting the website of your distribution and reading some of their documentation. The other thing to do is google for "how do I do BLAH in Ubuntu linux?" and see the results. Some distros have better documentation than others. Some prefer command line and text configuration while others have little "wizards" to help you get things setup and running.
You can download most distros as a *.iso file for free and then burn them to a CD to install (use "Burn Disc from Image" in whatever CD burning software you're using).
