get_posts may be easier for you to use:
$args = array( 'numberposts' => 5, 'category' => '3' );
$myposts = get_posts( $args );
foreach( $myposts as $post ) : setup_postdata($post); ?>
<div <?php post_class(); ?> id="post-<?php the_ID(); ?>" style="padding-bottom:5px;">
<h2><a href="https://wordpress.stackexchange.com/questions/22878/<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
<div class="post_meta"><?php twentyten_posted_on(); ?></div>
<div class="entryContent">
<?php the_content(); ?>
</div>
</div>
<?php endforeach; ?>
