Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

As far as I know you need a RHN subscription in order to upgrade RHEL. And that's a paying subscription if I'm not mistaking. Not sure if you need to add each and every server to the subscription or if you can use the same RHN login and connection for multiple servers.
You'll need a net cxn to RHN and a subscription for each machine. More accurately, 1 or more subscriptions (1 subscription can cover >1 system) that cover your machines, but each will need an entry in the RHN DB.
You do have to pay for these...
If you have this set up, then
as root user should do it. I'd recommend doing backups first; fyi current version is 5.4.
If you can't/won't pay, backup all non-OS stuff and install Centos 5.4 instead; it's a free version of RHEL.
