You can class each item individually and give them different paddings. For instance, if your menu is:
<ul>
<li id="homehp"><a href="<?php bloginfo('url'); ?>">Home</a></li>
<li id="listingshp"><a href="<?php bloginfo('url'); ?>/featured-listings">Featured Listings</a></li>
<li id="abouthp"><a href="<?php bloginfo('url'); ?>/about-julie">Why Choose Julie?</a></li>
<li id="piedmonthp"><a href="<?php bloginfo('url'); ?>/why-choose-piedmont">Why Choose Piedmont?</a></li>
<li id="clientshp"><a href="<?php bloginfo('url'); ?>/clients">Client Notes</a></li>
<li id="communityhp"><a href="<?php bloginfo('url'); ?>/community">Community Ties</a></li>
<li id="contacthp"><a href="<?php bloginfo('url'); ?>/contact">Contact Me</a></li>
</ul>
You can do stuff like this in the css:
#homehp {padding-top:10px;}
#listingshp {padding-top:5px;}
#abouthp {padding-top:0px;}
