Positioning issues in Aberdeen hack

Hi all,

Drupal noob here, using a hacked version of Aberdeen Liquid (thank you, whoever made Aberdeen; you rule and I'm a hack riding on your coattails). You can see it here:

Two problems that I can't figure out. First, at high resolution (1510 px or above, horizontal), the lefthand nav drops BELOW the main content area in the middle, but not at under 1510?? Need to use a clear or something?

Next, in Firefox, the rounded corners at the page bottom are separated from the bottom of the white page by a black line. I know what's causing it but not how to fix it. It's the code being executed in block.tpl.php that spits out this:

<div id="footer"> 
<div id="block-block-7" class="block block-block">  
  <div class="blockinner">
    <h2 class="title">  </h2>
    <div class="content">
      <p><a href="/drupal_spineu/index.php" title="Main Page">Home</a> | <a href="/drupal_spineu/spine_topics" title="Spine School">Spine School</a> | <a href="/drupal_spineu/spine_news" title="News">News</a> | <a href="/drupal_spineu/spine_faqs" title="FAQs">FAQs</a> | <a href="/drupal_spineu/forum" title="Discussions">Discussions</a> | <a href="/drupal_spineu/sitemenu/" title="Site Map">Site Map</a></p>
    </div>    
  </div>
</div>
</div>

I want it to just return this in the footer:

<p><a href="/drupal_spineu/index.php" title="Main Page">Home</a> | <a href="/drupal_spineu/spine_topics" title="Spine School">Spine School</a> | <a href="/drupal_spineu/spine_news" title="News">News</a> | <a href="/drupal_spineu/spine_faqs" title="FAQs">FAQs</a> | <a href="/drupal_spineu/forum" title="Discussions">Discussions</a> | <a href="/drupal_spineu/sitemenu/" title="Site Map">Site Map</a></p>

How do I alter the theme to do this (just for the footer) and any thoughts on the lefthand bar at high resolution would also be appreciated.

Thanks!
