Suckerfish Menu wp_list_pages Problems

I’m trying to simplify the code for my Suckerfish menu at this site TEK. The wp_list_pages and wp_list_categories add class attributes and is messing up my css formatting. here is my best stab at the code.

<div class="menuwrapper"><ul class="menu">
<li><a href="https://www.tekindoor.com/">HOME</a></li>

<li><a href="https://www.tekindoor.com/phpbb">FORUM</a>
<ul><?php wp_list_categories('title_li=&hide_empty=1'); old ?></ul></li>

<?php wp_list_pages('title_li=' ); ?>
</ul></div>
