Homebrew PCBs

Can someone direct me to a good guide to the Eagle software package.  It looks like it is very capable, but the information provided by eagle leaves a lot to be desired.  I'm looking for really basic information - for example, are the red circuit lines the component side or the solder side?  I can't find the answer to that anywhere in the manual, tutorial, or help files.  I think I can figure out how to establish the design rules, but if someone could save me a few hours digging around in the software it would be appreciated.

Thanks.
