Duplicate homepage grid and filter

I would like to create a new page with the same layout as the homepage grids but filtered on the post category. Ideas? I’ve created a new Page Template and tried to filter using the category ID however it doesn’t seem to work. I could get it to filter just the WordPress Loop however I like the grid layout.

Manually inserting the contents of Content.php hasn’t been going so well.

Thoughts? Below is the code I have so far (please disregard the “mobiletop” and “desktoptop” divs as I use those to set specific anchors when users navigate):

<?php /* Template Name: New Page Template */ ?>
<?php
/**
 * @package Gridster
 */
?>
<?php get_header(); ?>
<?php get_sidebar(); ?>

<div id="main">

<?php   query_posts('cat=169'); ?>
<?php if ( have_posts() ) : ?>
<?php /* Start the Loop */ ?>
<?php while ( have_posts() ) : the_post(); ?>
<div id="post-<?php the_ID(); ?>" <?php post_class("poste"); ?>> <a href="<?php the_permalink(); ?>" rel="bookmark">
<?php if ( has_post_thumbnail() ) {
the_post_thumbnail('post-thumb', array('class' => 'postimg'));
} else { ?>
<img src="<?php echo esc_url( get_template_directory_uri() ); ?>/img/defaultthumb.png" class="postimg" alt="<?php the_title(); ?>" /><?php } ?>
</a>
	
<div id="mobiletop">
<div class="portfoliooverlay"><a href="<?php the_permalink(); ?>#m"><!--<span>+</span>--></a></div>
</div>
<div id="desktoptop">
<div class="portfoliooverlay"><a href="<?php the_permalink(); ?>"><!--<span>+</span>--></a></div>
</div>
<h2 id="mobiletop" class="posttitle"><a href="<?php the_permalink(); ?>#m" rel="bookmark">
<?php the_title(); ?>
</a></h2>
<h2 id="desktoptop" class="posttitle"><a href="<?php the_permalink(); ?>" rel="bookmark">
<?php the_title(); ?>
</a></h2>

<p class="postmeta">
<?php if ( 'post' == get_post_type() ) : // Hide category and tag text for pages on Search ?>
<?php
				/* translators: used between list items, there is a space after the comma */
				$categories_list = get_the_category_list( __( ', ', 'gridster-lite' ) );
				if ( $categories_list && gridster_categorized_blog() ) :
			?>
<?php printf( __( '%1$s', 'gridster-lite' ), $categories_list ); ?>
<?php endif; // End if categories ?>
<?php endif; // End if 'post' == get_post_type() ?>
</p>
	
</div> <!-- content -->

<?php endwhile; // end of the loop. ?>
<?php get_footer(); ?>
