If you're using RH9 for server work, you have a good start.
I started with RH9 on my desktop (though my early linux experience was with RH7 at work and I had DOS ports of GNU software before that...)
Far from showing you havn't a clue, being here shows that you have got a clue... the trick is to participate. The whole point of GNU/Linux is that people share ideas and expertise as well as software. If you were clued up and hiding, you would be violating the spirit of FOSS. So welcome.
I would, however, suggest you change OS's soon. RH9 is obsolete and you'll increasingly find things will stop working quite the way you're used to.
For server things, strongly suggest a Debian distro. Ubuntu is a single-disk distro which is very newbie freindly and debian based.
If you prefer the red hat flavour - go for RHEL or Fedora Core depending on your support requirements. Good RH and fedora pages are at www.mjmwired.net
Suggested reading: google to the free software foundation and read the articles there. GPLv3 is in draft, and there is an old Stallman artical describing the basic philosophy wot you should know.
And, lastly, take a look at: http://www.zegeniestudios.net/ldc/
... good fun.
