If you want a good place for icons, you can have a look here:
http://interfacelift.com
It has a massive collection of great looking icons.
I'm not very artistic so tend to use them instead for my players as I can't draw or design for peanuts.
You will need an icon browser program to extract the icon files to an image file. I just use Photoshop to then do the editing.
Hope that helps.
