Front page links dont stay in category

I have a custom template page displaying as the first page. On this page I’m showing posts from the ‘whatsnew’ category. However, when I click on the “older entries” button at the page navigation links, it automatically takes me to the “all posts” page, which is the blog page.
How can I specify the navigation links to stay in the ‘whatsnew’ category?
I have several pages that show specific categories and they all behave this way when directed to display as front page.

See code below:

<?php
/*
Template Name: whatsnew
*/

get_header(); ?>
<div id=”content” class=”narrowcolumn”>
<div id=”custompageheader”>
<h1 class=”custompageheader”>
<?php the_title(); ?>
</h1>

</div>
<?php
$temp=$wp_query;
$wp_query=null;
$wp_query = new WP_Query();
$wp_query->query(‘showposts=5’ . ‘&cat=6’ . ‘&paged=’.$paged);

?>
<?php if( $wp_query->have_posts() ) : ?>
<?php while ($wp_query->have_posts()) : $wp_query->the_post(); ?>
<?php
//necessary to show the tags
global $wp_query;
$wp_query->in_the_loop = true;
?>
<div <?php post_class() ?> id=”post-<?php the_ID(); ?>”>
<?php if ( function_exists( ‘get_the_image’ ) ) { get_the_image(); } ?>
<h2>” rel=”bookmark” title=”Permanent Link to <?php the_title_attribute(); ?>”>
<?php the_title(); ?>
</h2>
<div class=”entry”>
<?php the_excerpt(); ?>

” title=”Read More”>Read More… </div>
<div id=”custompagepost”>
<div class=”custompagedate”>
<?php the_time(‘F jS, Y’) ?>
<!– by <?php the_author() ?> –>
</div>
<!–<?php the_tags(‘Tags: ‘, ‘, ‘, ‘
‘); ?>–>
<div class=”comments a”>
<?php edit_post_link(‘Edit’, ”, ‘ | ‘); ?>
<?php comments_popup_link(‘No Comments ?’, ‘1 Comment ?’, ‘% Comments ?’); ?>
</div>
</div>
</div>
<?php endwhile; ?>
<div class=”navigation”>
<div class=”alignleft”><?php next_posts_link(‘« Older Entries’) ?></div>
<div class=”alignright”><?php previous_posts_link(‘Newer Entries »’) ?></div>
</div>
<?php $wp_query = null; $wp_query = $temp;?>
<?php else : ?>
<h2 class=”center”>Not Found</h2>
<p class=”center”>Sorry, but you are looking for something that isn’t here.</p>
<?php get_search_form(); ?>
<?php endif; ?>
</div>
<?php get_sidebar(); ?>
<?php get_footer(); ?>

Thank you. I’d appreciate any input.
