I'm very pleased with the way it's come out as well!
We all loved the movie and are a bunch of Tolkien freaks.
And the forum is only just a piece, we've got a lot of sections, concerning artwork, the books, an armoury, etc....
As far as width, we have both the main table and content table to 100%, and our forum title width is 1000, we also have textarea widths at the bottom as IE 4+ = 70, Netscape Nav 4+ = 50, and Netscape 6+ = 40.
Hope this helps.
