Apparently 3 has gone end of life, but I've never upgraded a RHEL server before. I'm afraid of what might happen to my existing server. Does anyone have a good link to a doc on how to do this? Hopefully one that's in easy to understand terms ;-)

It's better to do a fresh installation and migrate your applications to the new system.
When upgrading major revisions 3.x to 5.x you are best off doing a bare bones install. You might also consider going to RHEL6.0 as it is now released and that will give you at least another five years until it has to done again.
You could copy a current installation to a staging server (virtualization?) and test an upgrade but in general I agree: 3 is way different compared to 5. A fresh install will cost you in terms of time and effort but will save some as well.
Unfortunately this is a server with multiple external arrays of data on it, so i'm not even sure where i could virtualize it to or anything to test. and i dont have the cash to buy a duplicate setup to build a new one either. :'(
Red Hat does not support in-place upgrades between any major versions of Red Hat Enterprise Linux. (A major version is denoted by a whole number version change. For example, Red Hat Enterprise Linux 5 and Red Hat Enterprise Linux 6 are both major versions of Red Hat Enterprise Linux).
