Well, I think that icons make the theme - since I blow in this theme making business - I've been working on composer for like a month now... here are a couple of websites where you may find stylish, sleek and most of all FREE icons.... hopefully some will work for you...

DryIcons.com - Free Icons and Vector Graphics
Free Icons Web - Free Icons,Free Icons Download,Free Desktop Icons,Royalty Free icons
Icon Archive - 25,700+ free icons, buddy icons, xp icons, vista icons, desktop icons, aim icons

There are probably many more websites out there - I am just pitching in a few...
