Take a look at this page, "http://www.eclipse.org/documentation/".

Then you may choose to buy a few books. I actually saw a book, http://my.safaribooksonline.com/9780470020050, that I think it looks OK. I don't have it tho.

You can search for more Java or Eclipse books on the site. I bought from them before and impressed with their service.

Have fun with Eclipse
