The aesthetic update is done for now. There are a couple more things I want to do, but they require changing the .ASPX files, and I wanted to see how far I could get with the new Chameleon stuff in Community Server 2007. Not too bad I guess. The CSS override option is what saved me. I found Firefox with the Developer Toolbar to be immensely valuable during that process. I was forever using the CSS > View Style Information to see what the current styles were for an element, so I could override them.
So the new look & feel is up, for now. Hope you like it.
