Problems with Twitter Sidebar

http://sandbox.wetwired.org/wordpress/

Im not the best at coding, so I’m having trouble with widgetized sidebar so to get around it I just created a separate sidebar that I am calling to load up my twitter updates:

<?php include(TEMPLATEPATH."/wetwired_sidebar.php"); ?>
And then the sidebar code:

<!-- Twitter Stuff -->
<div id="twitter_div">
<table width="87%" border="0" cellspacing="0" cellpadding="0">
            <tr>
              <td><ul id="twitter_update_list"></ul></td>
            </tr>
          </table>
</div>

<!-- End Twitter Stuff -->

The Java to load it is loaded later.
The damn thing keeps expanding and putting up scroll bars. I put a table in to try to constrain it more and still no go, I’m at a loss. Here is the CSS as well

#twitter_div {
background-image:url(images/twitter_sidebar_bak.png);
background-repeat:no-repeat;
width:324px;
overflow:auto;
}
#twitter_update_list {
width:324px;
padding-top:60px;
margin-right:100px;
height:365px;

}

Any thoughts?
