want to use dif. footer.php for page template – stuck how to link template to it

I want to use dif. footer.php for a page template.
The main page has 3 cols and want to have only 1. I use the copyblogger theme and have managed to hide the (right) sidebar but not the left.php file. The <?php include (‘left.php’); ?> line of code is in footer.php but when I try edit it out things go astray and lose the content of the page aswell.
My new page template code is this….

<?php
/*Template Name: shop-page
*/
?>
<?php include (‘shopheader.php’); ?>

<?php /*get_header();*/ ?>

<div id=”content_box”>

<div id=”content” class=”page”>

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

<h1><?php the_title(); ?></h1>
<div class=”entry”>
<?php the_content(‘<p>Read the rest of this page →</p>’); ?>
<?php link_pages(‘<p>Pages: ‘, ‘</p>’, ‘number’); ?>
</div>

<?php endwhile; endif; ?>

</div>

<?php /*get_sidebar(); */?>

</div>

<?php get_footer(); ?>

but php coding is weak to know how to link with new footer.php that has the left.php left out without breaking the content etc

I hope this make sense
can any one Help??
