To sort out the IE spacing problem, it's not a problem with other Browsers BTW, you can test adding this: <br class="clearBoth">

<li><a class="category-top" href="http://porterranchpharmacy.com/cart/index.php?main_page=index&amp;cPath=13">Zinnia Candles</a> </li>
</ul>
</div>
</div>
[ add it here first ]
<!--eof-optional categories tabs navigation display-->
</div>
[ add it here second if first doesn't work]


Also, perhaps you didn't notice that with your Navigation Menu, not all Categories are on one line? You need to sort that out as well.
