How To create a blank page template with center page content only

Hi,
I've been trying to understand how to create a page template that only displays the content we enter into the back end editor's content box when we add a new page. (No blog title/menus, no sidebars -- just a plain white background.)

We will be using this template for a store "pitch" page using our estore plugin, so it does need to function inside Wordpress.

How might I accomplish this?


Also, I'd like to be able to link it to the stylesheet but override certain styles with custom styles for this page. I assume I can define custom styles with CSS between the style tags in the custom template. Is that correct?

Thanks!

Michael
