query_posts

I am currently using:

<?php	if (post_type_exists('athlete')) {
              query_posts(array( 'post_type'=>'athlete', 'showposts'=>-1, ));
            }
            while ( have_posts() ) : the_post();
                $data = get_posts();?>
				<h4> <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h4>
            <?php endwhile; ?>

To pull a list of all of the “Athlete” posts onto a page.

What I would like to do is sort by last name which I currently have set up as a metabox field called “athlete_lname” and then display the athletes name in a two column list on the page.

The theme currently has css setup for two columns “two-col1” and “two-col2”

Thanks in advance for anyone’s help on this,
