Static pages from HTML

I am creating some static pages from HTML page designs, and I simply want to drop them into a 1000px wide blank page. Basically a 1000px 3-column table.
This is the template page I am using:

<?php
/*
Template Name: jemastatic
*/
?>
<?php

get_header(); ?>

<?php the_post(); ?>

<?php get_template_part( 'content', 'page' ); ?>

<?php comments_template( '', true ); ?>

<?php get_footer(); ?>

Now what I get is a narrower page that screws up the design, taking width from the first column.

Site is swimmingpoolliftada.com

Using Web Developer, everything works fine if I delete the following lines from the displayed HTML –

<article id="post-74" class="post-74 page type-page status-publish hentry">
	<header class="entry-header">
		<h1 class="entry-title">Door</h1>
	</header><!-- .entry-header -->

	<div class="entry-content">

I can’t figure where these lines are added from. The header ends with #Main, and the footer begins with close #main. In between I expect nothing but what I put into the page edit box.
I have been sweating this for a week, and would be grateful for solutions. (I also need to get rid of the extra page title, which also goes away with the deleted lines.)
Thanks for your help!
