Have you looked at the tutorials within Eclipse itself?

Just click on Help/Welcome and you should see a page with 4 large icons (I'm
using Eclipse 3.1.1; if you are on a different version of Eclipse, you may
see something slightly different.). The leftmost icon is a globe on a stand
and if you do a mouseover, the help bubble tells you that it is an overview
of Eclipse. The second icon from the left is a chalkboard and if you do a
mouseover, the help button tells you it leads to Eclipse tutorials. The
other two icons may also be interesting to you.

I've been using Eclipse for a few years now and the Help system was very
skimpy when I started out but there was still enough information in it for
me to learn the basics of using Eclipse in just a few hours. With all of the
information that has been added since that time, I think there's a very good
chance that you can learn all or most of what you need from the Eclipse help
system without having to go elsewhere. After all, they've probably paid
several Eclipse employees good money to write decent tutorials and
documentation on using Eclipse :-)
