Before you put time in learning Photoshop maybe you can try Adobe Fireworks first, which is Adobes "web designer" product. It's much more intuitive than Photoshop, which I never managed to get around with, no layer stuff etc. Just draw, paint and put your objects on the canvas, it manages the layers automagically. Fireworks combines vector and bitmap graphics, you can open and save PSD files and for web design purposes I did not miss anything yet. Also it's much cheaper (around 300 USD?). I guess you can start playing with it with no tutorial, but of course there are resources like http://www.fireworkszone.com/ or http://www.entheosweb.com/fireworks/default.asp. And they regularly post resources on their Facebook channel https://www.facebook.com/AdobeFireworks

If you are using Windows, an alternative cheaper option is Microsoft's Expression Design which is great for web and UI design and can often be picked up cheaply online (plus it has a rather generous 60-day trial).
