You specify a static home page in WP, not the theme.

There's an issue with using a static home page and the feature area.  You can modify the index.php file to show the feature on all pages by changing this:

 <?php if ($flex_feat_display == "no") { ?>
       <?php } else { ?>
       <?php if ( is_front_page())  { ?>
            <div id="feature"><div class="topshadow">
            <?php if ( function_exists('dynamic_sidebar') && dynamic_sidebar('Feature_top') ) : else : ?>
               <?php include (TEMPLATEPATH . '/feature.php'); ?>   
            <?php endif; ?><div style="clear:both;"></div>
    </div></div>
       <?php } else { ?>
    <?php } ?>
    <?php } ?>

To this:

 
            <div id="feature"><div class="topshadow">
            <?php if ( function_exists('dynamic_sidebar') && dynamic_sidebar('Feature_top') ) : else : ?>
               <?php include (TEMPLATEPATH . '/feature.php'); ?>   
            <?php endif; ?><div style="clear:both;"></div>
    </div></div>

You could use a "exclude pages" plugin to remove it from your nav bar, then use a no-index plugin to no-index the duplicate page.
