SickFox on "How to display single Portfolio Category in a Portfolio page"

Hi, I've been looking through the forums but as I'm very new to WP I'm not having much luck. Any help would be most grateful.

The current portfolio template displays all categories, I wish for it to only display one "Store". So in essence I can create different portfolios over different pages.

Here's the code:

<?php
/*
Template Name: Test Portfolio
*/
?>
<?php get_header();?>
<?php
$meta = icore_get_multimeta(array('Subheader'));
?>
<div id="entry-full">
    <div id="page-top">
    	<h1 class="title">Test Portfolio</h1>
    	<?php if( isset($meta['Subheader'] ) && $meta['Subheader'] <> '') { ?>
        	<span class="subheader"><?php echo $meta['Subheader']; ?></span>
    	<?php } ?>
    </div> <!-- #page-top  -->

	<div id="left" class="full-width">

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

		<?php
	    $args = array(
			'post_type'=>'portfolio',
			'paged' => $paged
	    );

	    $temp = $wp_query;
	    $wp_query = null;
	    $wp_query = new WP_Query();
	    $wp_query->query( $args );
	    ?>

		<?php if ( $wp_query->have_posts() ) : ?>

	    	<div class="galleries">
				<div class="three-column">

		        <?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?>
		    		<?php $do_not_duplicate = $post->ID; ?>

		    		<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
						<div class="gallery-image-wrap">
							<?php if ( has_post_thumbnail() ) { ?>
								<?php $thumbid = get_post_thumbnail_id($post->ID);
									  $img = wp_get_attachment_image_src($thumbid,'full');
									  $img['title'] = get_the_title($thumbid); ?>

									  <?php the_post_thumbnail("gallery-thumb"); ?>

									  <a href="<?php echo $img[0]; ?>" class="zoom-icon" rel="shadowbox" ></a>
									  <a href="<?php the_permalink(); ?>" class="link-icon"></a>
							<?php } else { ?>
									  <a href="<?php the_permalink(); ?>">
									  <?php echo '<img src="'.get_stylesheet_directory_uri().'/images/no-portfolio-archive.png" class="wp-post-image"/>'; ?>			</a>
							<?php } ?>
							<?php $args = array(
								'post_type' 	=> 'attachment',
								'numberposts' 	=> -1,
								'post_status' 	=> null,
								'post_parent' 	=> $post->ID,
								'post_mime_type'=> 'image',
								'orderby'		=> 'menu_order',
								'order'			=> 'ASC'
							);
							$attachments = get_posts($args);
							$count = count($attachments); ?>

							<?php if ( $count > 1 ) { ?>
								<span class="image-count"><?php echo $count . __(' Images', 'InterStellar'); ?></span>
							<?php } ?>

						</div>
						<h2 class="gallery-title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
						<?php the_excerpt(); ?>
					</article><!-- #post-<?php the_ID(); ?> -->

				<?php endwhile; ?>

				</div>
			</div> <!-- .galleries -->

			<?php get_template_part( 'navigation', 'index' ); ?>

		<?php else : ?>

			<?php get_template_part( 'no-results', 'index' ); ?>

	<?php endif; ?>

	</div> <!--  end #left  -->
</div> <!-- #entry-full  -->
<?php get_footer(); ?>

Many thanks again.
