ThanksI get most of my desktop images from this site, http://interfacelift.com/wallpaper/
I use the Dreamland theme from wincustomize.com, right now i'm using windowsblinds but there's a way to hack windows so you don't need to use the third party software. Someone posted the link earlier i believe.
The clock and other widgets are from avedesk, http://www.avedesk.org/. Most of the desklets came with the software, but the clock specifically is from the downloads page. I used this app to replace my desktop icons as well.
Hope that helps. ^_^
