I have found that it helps a lot when googling for information, to include "how-to" or "tutorial" as a search term, in addition to the keywords for what you are looking for.
The following are good sites for down-to-earth basic information on Linux. I have included Unix articles as commands are the same.
Great Linux Newbie Tutorial Sites

If you do not have a console or terminal already installed on your Zaurus, then read this.
For how-tos for the Zaurus, check out the Zaurus_How-To_Docs page at oesf.
For Zaurus forums, go to http://www.oesf.org/forum or to http://tyrannozaurus.com.
For Zaurus IRC chat, check out #zaurus and #openembedded at irc.freenode.net. Be sure to go when you have time to stick around (i.e., leave your Zaurus's chat client open) at least a half hour. If you have a straightforward Zaurus or OZ question, then go ahead and *ask* and then check your client every five or ten minutes for responses.
I know how overwhelming it can be for a newbie to get too much information at once, to go on overload, so I am limiting the listings above to my favorite resources. If you want more options, or the above do not provide you with the level of help that you need or want, then check out the other how-to's and introductions that I have described in my blog:
