Different page layout for one page

I would like to put this one page in a different format — to replace all the links in the right hand sidebar with one section of text.

How can I change this one page to a two-column format without the sidebar? Or, I can I create a text widget for this one page and substitute it (only on this one page) for the widgets that are there now?

Thanks for your pointers!

The page I need help with: [log in to see the link]
