If you want to learn Photoshop, I highly recommend the book Layers by Matt Kloskowski. However, the right book depends on how you prefer to learn. I like the previously mentioned book because it has short chapters, each demonstrating a technique that I can try out on my own photos. Some people recommend the Classroom in a Book series by Adobe Press as a good starting point for beginners. It is a good idea to study the reader reviews on a site like Amazon.com before buying a Photoshop book, so you can see the pros and cons of each book and can choose the one that suits your learning style and experience.
Many people find video trainings less tedious than using a book. There are loads of free trainings available on the Internet, but not all are suitable for beginners. Training sites like Lynda.com or Kelbytraining.com offer subscription based trainings and it might be worthwhile for you to subscribe for a month (when you have a lot of time). Kelbytraining.com is devoted to Photoshop and Photography, whereas Lynda.com covers many different products and technologies, including Photoshop Elements.
Elements 6 is pretty outdated, upgrade to 10, it's cheap.
