But a dump of the site's contents (basically the directory(s) on the web server where all your stuff is) could be very useful for people wanting to help redesign...

For instance, when I was doing the tab thing (which I don't think you have 100% right because it should have been black background with that cream colored text) I was using web developer (or firebug) in firefox to pull the colors off the site... With all the graphics and whatnot available, I could do a lot more. While I *could* get that stuff myself, it'd be a lot easier with your aid (not to mention keeping the structure intact).

Also, I am by no means even 1% the web guru that some of our other people are, and they might be more willing to step up if they had something more to work with.
