Need help getting a featured slider to work on individual categories

I have a featured slider on my page here - http://chrispriddy.com that only appears on the first page.

I want to take it to the categories page (like here - http://chrispriddy.com/category/3d-stills/ ), and call the category to use as the primary info on that page.

I am using the ePhoto theme from elegantthemes.com. Here is the code in the "featured.php" -

<?php $feat_cat = get_catId(get_option('ephoto_feat_cat')); ?>
<div style="clear: both;"></div>
<div class="featured">
    <div id="sections">
        <ul><?php $ids = array(); ?>
            <?php $my_query = new WP_Query("cat=$feat_cat&showposts=$ephoto_homepage_featured;");
while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID; ?>
            
			<?php $width = 655;
				  $height = 364;
				  $classtext = '';
				  $titletext = get_the_title();
					
				  $thumbnail = get_thumbnail($width,$height,$classtext,$titletext,$titletext,true);
				  $thumb = $thumbnail["thumb"]; ?>
			
            <li style="background-image: url('<?php print_thumbnail($thumb, $thumbnail["use_timthumb"], $titletext, $width, $height, '', true, true); ?>');">
                <div class="sections-overlay">
					<?php $video = get_post_meta($post->ID, 'Video', $single = true); ?>
					<?php if($video <> '') : ?>
						<a href="<?php the_permalink() ?>" title="<?php the_title() ?>"><img src="<?php bloginfo('template_directory'); ?>/images/play.png" alt="zoom" class="zoom" /></a>
					<?php else : ?>
						<a href="<?php echo $thumbnail["fullpath"]; ?>" title="<?php the_title() ?>" rel="lightbox[26]"><img src="<?php bloginfo('template_directory'); ?>/images/zoom.png" alt="zoom" class="zoom" /></a>
					<?php endif; ?>
                </div>
            </li>
			
			<?php $ids[]= $post->ID; ?>
            <?php endwhile; wp_reset_query(); ?>
        </ul>
    </div> <!-- -end sections -->
    <div id="featured-right">
        <div id="sections2">
            <ul>
                <?php $my_query = new WP_Query("cat=$feat_cat&showposts=$ephoto_homepage_featured;");
while ($my_query->have_posts()) : $my_query->the_post();
$do_not_duplicate = $post->ID; ?>
                <?php $thumb = get_post_meta($post->ID, 'Thumbnail', $single = true);?>
                <li>
                    <h2 class="featured-title"><a href="<?php the_permalink() ?>" title="<?php printf(__('Permanent Link to %s','ePhoto'), get_the_title()) ?>">
                        <?php truncate_title(20) ?>
                        </a></h2>
                    <div class="featured-info"><?php _e('Posted by','ePhoto') ?>
                        <?php the_author() ?>
                        |
                        <?php the_time(get_option('ephoto_date_format')) ?>
                    </div>
                    <?php truncate_post(250); ?>
                    <div style="clear: both;"></div>
                    <a href="<?php the_permalink() ?>" class="featured-readmore"><?php _e('read more','ePhoto') ?></a> </li>
                <?php endwhile; wp_reset_query(); ?>
            </ul>
        </div> <!-- -end sections2 -->
        <div style="clear: both;"></div>
        <div id="featured-button">
            <div class="prev">
                <div class="prev-hover"> </div>
            </div>
            <div class="next">
                <div class="next-hover"></div>
            </div>
        </div> <!-- -end featured-bottom -->
    </div> <!-- -end featured-right -->
</div> <!-- -end featured -->

PHP:

So to rehash, I want to change this from featured to call the category that the pics are in. I see there are a lot of things telling this to use the "featured post", which I choose in the back end of my theme.
