Hi,
LINUX can be frustrating at first, since you are at the mercy of a new OS
where everything will naturally appear foreign at first. There are many books
out there, and lots of stuff on the net as well.
I once bought "The Redhat 7.1 Bible", which included the RH7.1 as well, so
everything in the book "just worked". It was a big book, and covered much more
than I wanted to learn at first, but it was divided well, and I could jump around
from concept to concept easily.
I find the Slackware Book, found at
http://www.slackbook.org/ (view the single page
version if you have the resources) as a very good starting point currently.
Also, you may want to find a decent Live CD of a decent linux, such as knoppix, to
play around on a desktop machine, which will be more comfortable with a larger
screen, keyboard, and a real mouse. And Live CDs do not require you to install
anything to your desktop, as they run from memory.
