The unequal height between the tabs and their parent container is basically due to the CSS for the Shade Tabs itself. While you can tweak the CSS to try and make it behave the way you want, an easier way perhaps is just to swap out that CSS with something you know comes close to what you have in mind already.
Looking at your page, Matt Tabs Menu seems like a good fit. Using it, first, replace the original tabcontent.css file with the attached, then, replace the HTML for your main tabs with the slightly altered one below:
Code:
<div class="mattblacktabs">
<ul id="countrytabs">
<li><a href="#" rel="country1" class="selected">All</a></li>
<li><a href="#" rel="country2">Suns</a></li>
<li><a href="#" rel="country3">D-Backs</a></li>
<li><a href="#" rel="country4">Cardinals</a></li>
<li><a href="http://www.azfans.com/forums">More</a></li>
</ul>
</div>
