no, you just need to put your sticky post in your div,
Place the following code just before the loop:
<div class="postUp">
<?php
$sticky = get_option('sticky_posts');
rsort( $sticky );
$sticky = array_slice( $sticky, 0, 5);
query_posts( array( 'post__in' => $sticky, 'caller_get_posts' => 1 ) );
?>
</div>
This code will retrieve the 5 most recent sticky posts. To change the number of retrieved posts, just change the 5 by the desired value on line 4.
