How do I arrange my Navigation?

Here is my under-construction site:
https://rockwell.jobsversity.com

My navigation works like this:
Enter the ID of the page you DONT WANT to include in the nav. Its working perfectly in this part. The problem is I cant re-arrange the navigation.

I want to arrange like this:
About, Portfolio, Blog, Forum, Contact (sample page is not included)

<div id="topnav" class="jqueryslidemenu">
<ul>
<li><a <?php if (is_home()) : ?>class="currentHome"<?php else : ?>class="home"<?php endif ?> href="<?php bloginfo('url'); ?>/">Home</a></li>

<?php
$sk_exclude_pg = get_option('sk_exclude_pg'); wp_list_pages('title_li=&exclude=' . $sk_exclude_pg . '');
?>
</ul>
<br style="clear:left" />
</div>	<!-- close #topnav -->
