help with archives...

Hey all, I'm having some difficulty with my archives page showing a "previous" posts link or anything like that. The code is showing the latest posts as well as limiting the number I want to show. The problem is, if there is more than the amount of posts on the page, how can I have a next button or something to show the other posts minus the first ones?

<?php
/*
Template Name: Archive
*/
?>
<?php get_header(); ?>
<?php include(TEMPLATEPATH . '/banner.php'); ?>
<div id="content">
<div id="content_tp">
<div class="wrap">
			<?php $my_query = new WP_Query('category_name=&posts_per_page=3');
                    while ($my_query->have_posts()) : $my_query->the_post();
                    $do_not_duplicate = $post->ID;?>
		                   
                 		<div class="post2">
                	    <h3><?php the_title(); ?></h3>
				<h4><?php the_time('l, F jS, Y') ?></h4>
                   	    <p><?php the_content_limit(200, "Read More") ?><p>
			        </div>
		<?php endwhile; ?>  
		<div class="navigation">
        <div class="alignleft"><?php next_posts_link('&laquo; Older Entries') ?></div>
        <div class="alignright"><?php previous_posts_link('Newer Entries &raquo;') ?></div>
        </div>
<div class="clear"><!-- --></div>
        
<?php include(TEMPLATEPATH . '/recommend.php'); ?>
        
        </div><!--wrap -->    
    
    </div><!--content_tp -->
    <div id="content_bt"><!-- --></div>
    </div><!--content -->

</div><!--wrapper -->

<?php get_footer(); ?>
