I have made a ridiculously long post with lots of ideas and tips on icon making. It's full of links to other tutorials and general tips on how to make neat-o icons.

*Be warned that it's quite image heavy and therefore isn't the most dial-up friendly. ;)

I have also made a tutorial on making headers here.

Both are for PS7, but i'm pretty sure the concepts can be translated to other programs.
