A little fumbling around and I think I have solved both of the above questions!

Still need lots of help though!

The Valid XHTML 1.0 Transitional message below the footer.... any idea where this is located? I'd like to remove that also!

Another change I would like to make, would be to move the top bar (with login etc), to below the header image. Is it just a case or renaming that nav or more than that (eg the css)?

Cheers
