If just starting out, get comfortable with the fact that you’re eventually going to spend way more on self-study material than you spent on PS itself. Why? Because the more you learn, the more you’re going to want to learn and the learning is endless. A compete book on Photoshop would be at least a mile thick – I’m not kidding… it’s hands down the coolest app in the world ever.
If you’re brand new to PS, I recommend you buy the DVD training series here > <

However if you’re like me and you aren’t brand new to PS but still see yourself on the bottom rung, Google some filter searches, go to Russell Brown’s website and download his free QT tutorials, visit yet the many other PS tutorial websites and print them out.
I also have books by Kelby, Eismann, Jack Davis, Willmore, McClelland, etc that I go back to over and over again. Yes, it’s a bit nuts but its fun too. I might have saved myself a few bucks at the beginning by taking out a second mortgage on my house and negotiating a deal with Amazon.com/books. = ^ )
