customizing TwentyEleven comments template

Typically I don’t utilize comments on my sites, however I’m using the comments functionality as a sort of live-feed testimonials page. To do this, I’ve borrowed comments.php and the comments portion of functions.php from the TwentyEleven theme.
What I’m currently struggling with is how the comments/form are displaying on the site
Ideally, I’d like the form to be on the left (inside .content-left) and the list of comments to be on the right (inside .content-right). Currently, the list of comments is both above the form in .content-left and where I’d like it to be in .content-right. How do I remove it from the left?

share.php

<?php
/*

<?php get_header(); ?>

<h1>We're All Ears.</h1>
<div class="content-left">

    <?php comments_template(); ?> 

</div><!-- end content-left -->
<div class="content-right">

    <?php wp_list_comments( array( 'callback' => 'twentyeleven_comment' )); ?></ul>

</div><!-- end content-right -->

<?php get_footer(); ?>

comments.php

<?php
/**

    <div id="comments">
    <?php if ( post_password_required() ) : ?>
        <p class="nopassword"><?php _e( 'This post is password protected. Enter the password to view any comments.', 'twentyeleven' ); ?></p>
    </div><!-- #comments -->
    <?php
            /* Stop the rest of comments.php from being processed,
             * but don't kill the script entirely -- we still have

Also, how can I go have the comment list display the user name as well as the info from the other fields?
