I still vote for this book if you are a raw beginner: "Create!: The No Nonsense Guide to Photoshop Elements 2" by Greg Simsic, Katy Bodenmiller. Small book (small price) that covers all the basics, very clear writing style, practice exercises.
Combine the above book with Jay Arraich’s tool, palette and blend mode explanations and the article "Why Layers?": <

Next, buy Mikel Aaland’s book, Gregory Georges’ book and Scott Kelby’s if you like.
Sit back and realize with great pride that you now have just spent more on books then for the software. The good news is you’ve learned just about everything in Elements now and if you forget, you can look it up. 🙂
To be quite honest, I probably learned more from Arraich’s site and this forum in the beginning than from any of the books. But I DO love my books! I have only 8 books on Photoshop Elements/Photoshop now. Still learning more each day.
