Woah! Red Hat 9 was discontinued years ago. The closest thing to a free Red Hat Linux is the
Fedora Project. A community effort sponsored by Red Hat. Be warned, Fedora is a bleeding-edge distribution. It is very current, but also occasionally buggy.
If you are just starting out, you may want a more stable "desktop" distribution, like Ubuntu or SUSE.
Distrowatch has links to reviews and the various download sites. Most of these distros have bootable CD's available so you can
test drive before you install.
