Bigcommerce order confirmation page: Formatting problems

We are in the late stages of setting up our site on the BigCommerce platform. The order confirmation page has various formatting problems: 1. HEADER: Make same width as homepage (see attached screenshot): All other pages on our site have a wide header which is a row of images: See: [login to view URL] But on the order confirmation page (after checkout process) has a narrow header format which messes up the format of our custom header (which is designed to stretch across the 100% width of the screen). 2. Blank space where confirmation info should be (see attached screenshot) 3. RSS feed appears in left sidebar: We do not want an RSS feed to appear anywhere on this page. 4. Order info appears among parts of RSS feed and a misplaced image from the footer (BBB image - see attached screenshot) 5. Footer formatting is all messed up - see attached screenshots. The footer on this page should look the same as the footer on the homepage. This project is to fix all of the problems numbered 1 through 5 above, and to remove the RSS feed completely from this order confirmation page. You can see the order confirmation page by checking out on the site, using check as payment method so that you do not have to pay anything during checkout and can proceed all the way to the order confirmation page.
