Template to Display All Posts in Custom Post Type and Custom Taxonomy

Hello all. I’m having some trouble displaying the posts in a custom post type on my portfolio site, and I’m wondering if someone can help.

Here’s the deal. I have a custom post type called ‘work.’ Within that custom post type, I have a custom taxonomy called ‘project type’ where I have created several categories called photography, video, print design, etc. I set up a template called taxonomy.php which governs mydomain.com/work as well as mydomain.com/project-type/print-design/. The problem is that these pages only display the 5 most recent posts. I need them to display all the posts in the proper category (or in the case of mydomain.com/work, all of the posts in the custom post type regardless of category). How can I modify this code to display all of the posts?

Here is the code I have used for taxonomy.php:

<?php

/**
 * Project Type Taxonomy Archive
 */

$term = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );
?>

<h3 style="color:#EEEEEE"><?php echo apply_filters( 'the_title', $term->name ); ?> PROJECTS</h3>

<ul class="thumbnails">
	<div id="work">

		<?php if ( !empty( $term->description ) ): ?>
		<div class="archive-description">
			<?php echo esc_html($term->description); ?>
		</div>
		<?php endif; ?>

		<?php if ( have_posts() ): while ( have_posts() ): the_post(); ?>

		<div class="post">
			<li class="span4">
				<div class="thumbnail">
				<a href="<?php the_permalink() ?>"><div class="tint"><?php the_post_thumbnail( 'featured-thumb' ); ?></div></a>
				<br />
				<div class="thumbcaption">
					<a href="<?php the_permalink() ?>"><h3><?php the_title() ?></h3></a>
					<p>	<?php the_excerpt(); ?></p>
					<p><i><?php the_terms( $post->ID, 'work_project_type' ,  ' ' ); ?></i></p>
				</div>
				</div>
			</li>
		</div>

		<?php endwhile; ?>

		<div class="navigation clearfix">
			<div class="alignleft"><?php next_posts_link('« Previous Entries') ?></div>
			<div class="alignright"><?php previous_posts_link('Next Entries »') ?></div>
		</div>

		<?php else: ?>

		<h2 class="post-title">No Projects in <?php echo apply_filters( 'the_title', $term->name ); ?></h2>
		<div class="content clearfix">
			<div class="entry">
				<p>It seems there aren't any projects in <strong><?php echo apply_filters( 'the_title', $term->name ); ?></strong> right now. Check back later, I try to add new projects regularly.</p>
			</div>
		</div>

		<?php endif; ?>
	</div>
	</div>
</ul>

Here’s the link to the work page and here’s a link to a category page. Thanks for your help.
