Trying to remove extra menus

I'm stuck on an issue. The website address is rvwholesalenetwork.com , if you would be kind enough to login, you'll see the two issues I refer to below.

The page that loads is what I want the home page to be - a listing form.

Please note the black band near the top of the page. It contains buttons that start with "sample page" and end with "password reset". I'd like to eliminate most of those buttons (and/or potentially move a few of them to a header to aid in navigation). How can I do this?

Thanks for all your help and assistance,

Alan Sills
