Multiple Loops?

I want to create multiple loops.
Showing the three newest posts with one style and the rest with another.
Note that I only display posts from category. Could someone help me and modify the code?

<?php if (have_posts()) : ?>
<?php query_posts('category_name=front=3'); ?>
<?php while (have_posts()) : the_post(); ?>
<div class="container">
<a>">
<div class="box">
<div class="shadowtitle"><?php the_title(); ?></div>
<font class="shadowtime"><?php the_time('D j, Y'); ?> | Posted by <?php the_author(); ?></font></div></a>
<div style="clear:both;">
</div>
</div>
<div style="clear:both;"></div>
<?php endwhile; ?>
