Multiple Loops in Navigation With Get_Posts

I’ve got a dynamic fly-out menu setup for my navigation, and I’m using get_posts to pull in posts in each category. Unfortunately, it’s thrown off my main loop and now it’s trying to load the last post from the navigation for every post (there’s no post under that category yet).

Don’t have too much experience running multiple loops, so this may well be a simple fix that I’ve overlooking.

Here’s the navigation code:

<ul id="topnav">
    <li><a href="/category/features/" class="features">Features</a>
        <div class="sub">
            <ul>
                <li><h2><a href="/category/features/culture/">Culture</a></h2></li>
<?php
 global $post;
 $tmp_post = $post;
 $myposts = get_posts('numberposts=2&offset=0&category=588');
 foreach($myposts as $post) :
   setup_postdata($post);
 ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
 <?php endforeach; ?>
            </ul>
            <ul>
                <li><h2><a href="/category/features/music/">Music</a></h2></li>
<?php
 global $post;
 $myposts = get_posts('numberposts=2&offset=0&category=586');
 foreach($myposts as $post) :
   setup_postdata($post);
 ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
 <?php endforeach; ?>
            </ul>
            <ul>
                <li><h2><a href="/category/features/fashion/">Fashion</a></h2></li>
<?php
 global $post;
 $myposts = get_posts('numberposts=2&offset=0&category=587');
 foreach($myposts as $post) :
   setup_postdata($post);
 ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
 <?php endforeach; ?>
            </ul>
            <ul>
                <li><h2><a href="/category/features/photographs/">Photos</a></h2></li>
<?php
 global $post;
 $myposts = get_posts('numberposts=2&offset=0&category=605');
 foreach($myposts as $post) :
   setup_postdata($post);
 ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>

and here’s the page code, for a news post:

			<p>Sorry, but you are looking for something that isn't here.</p>
			<?php include (TEMPLATEPATH . "/searchform.php"); ?>
<?php endif; ?>

</div>
</div>
<?php include('sidebar-news.php'); ?>
<div id="clearer"></div></div><?php include('footernew.php') ?>

I feel like the issue is a fairly obvious one with the way I’ve set up my main loop, but I can’t for the life of me figure out what I need to change to correct it.

I need help ASAP so I can get my site (https://abovegroundmagazine.com) back into working order.

Thanks!
