The basic answer for anyone else is something along these lines (this is for the header include, repeat for sidebar, footer, etc.):
<?php
if(is_page('id-of-special-page-here')) {
include('special-header.php');
} else {
get_header();
}
?>
Make sure you have actually created your 'special-header.php' file, etc, and replace the regular <?php get_header(); ?> call with the above.
