This is a long thread, but it should have the answers you're looking for: http://themeshaper.com/forums/topic/something-new-bout-widgetized-areas
You'll probably want to rename the "Primary" and "Secondary" widget area to something that makes more sense. Then register a new widget area, that will go below those two and hook it in. The arrangement can all be handled by css.
I know this is a little vague, but if you have trouble post again. Here's some sample code I used in a project. It's used for a different purpose, but might be helpful so you can see how different areas are registered and renamed and called:
// Defining Widget Areas
function remove_widget_areas($content) {
unset($content['Index Insert']);
unset($content['Single Insert']);
unset($content['Index Top']);
unset($content['Index Bottom']);
unset($content['Single Top']);
unset($content['Single Bottom']);
unset($content['Page Top']);
unset($content['Page Bottom']);
return $content;
}
add_filter('thematic_widgetized_areas', 'remove_widget_areas');
// Renaming and Changing Functionality
function rename_widgetized_areas($content) {
$content['Primary Aside']['args']['name'] = 'Image Rotator';
$content['Secondary Aside']['args']['name'] = 'Page Sidebar';
$content['Secondary Aside']['args']['description'] = 'This widget area appears on pages but not posts.';
$content['1st Subsidiary Aside']['args']['name'] = 'Footer First';
$content['2nd Subsidiary Aside']['args']['name'] = 'Footer Second';
$content['3rd Subsidiary Aside']['args']['name'] = 'Footer Third';
$content['Secondary Aside']['function'] = 'childtheme_secondary_aside';
return $content;
}
add_filter('thematic_widgetized_areas', 'rename_widgetized_areas');
// Register Fourth Footer Widget Area
function add_fourth_subsidiary(){
register_sidebar(array(
'name' => 'Footer Fourth',
'id' => '4th-subsidiary-aside',
'before_widget' => '<li id="%1$s" class="widgetcontainer %2$s">',
'after_widget' => "</li>",
'before_title' => thematic_before_title(),
'after_title' => thematic_after_title(),
));
}
add_action('init','add_fourth_subsidiary');
// Output Fourth Footer Widget Area
function output_fourth_subsidiary(){
if ( is_sidebar_active('4th-subsidiary-aside') ) { // there are active widgets for this aside
echo '<div id="fourth" class="aside sub-aside">'. "\n" . '<ul class="xoxo">' . "\n";
dynamic_sidebar('4th-subsidiary-aside');
echo '</ul>' . "\n" . '</div><!-- #fourth .aside -->'. "\n";
