Right side column - 100% width footer?

I posted this at vb.com as well but hopefully someone here can bail me out of hours of staring at the code and breaking my poor forums.

I've read the tutorials on here and they're all seemingly for adding a RSC that spans the entire length of the page. Has anyone done it so that it's only the height of the actual forums? Using Kerry-Anne's USC mod over at vb.org, the RSC starts exactly where I want it to and looks great (See attachment). The problem is that my footer, what's going on box, etc, is compressed to the width of the forum tables themselves, leaving blank space to the side of the WGO box, under the column itself.

I'm looking for the exact TOP setup that Kerry-Anne's USC provides, but I want the colum to stop before my footer, and have the footer span 100% width, same as the navbar.

So:

----------navbar---------
----forums ----- rsc -----
---------footer ----------

If anyone can sort out the code for this and hook me up, Boofo will email you a box of puppies*.
