looks like a lot of good information, but way over my head at this time.

I see in a previous post you said your using Ubuntu. Being new to Linux with allot of information and not knowing where to start can be overwhelming. Here's some suggestions, not in any particular order, just in case you haven't seen them:

Common Questions
https://help.ubuntu.com/community/CommonQuestions
Ubuntu Screencasts
http://screencasts.ubuntu.com/
Installation
https://help.ubuntu.com/community/Installation

This book was one of the first Linux books I purchased:

Running Linux, Fifth Edition
http://oreilly.com/catalog/9780596007607/

Here's one for Ubuntu beginners:

Ubuntu for Non-Geeks, Second Edition
http://oreilly.com/catalog/9781593271527/

There's probably lots more books to choice from.

If you have a particular question, then just post that in a new thread.
