Query post in "

Hey, i need an another help, i have implemented a query function in <div id=”slider_on”> which allows a post from category ID 6, there only one post, then the pagination doesn’t work =(

There is a snippet of index.php:

<?php get_header(); ?>
<div id="fronter"></div>
<div id="lines"></div>
<div id="slider_area">
<div id="wrapsli">
<div id="lefts">
</div>
<div id="slider_on">

<?php query_posts('cat=6&showposts='.get_option('posts_per_page')); ?>
		<?php if (have_posts()) : ?>

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

					<h2><?php the_title(); ?></h2>

					<div class="entry">
						<?php the_content() ?>
					</div>

		<?php endwhile; ?>	

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

	<div id="rights">
	</div>
</div>

</div>
<div id="lines"></div>
<div id="wrap">

		<div class="col1">

		    <?php
		    if (is_paged()) $is_paged = true;

		     $paged = (get_query_var('paged')) ? get_query_var('paged') : 0;
             $args = array(
               'post__not_in' => $shownslides,
               'tag__not_in' => $tagids,
               'paged'=> $paged
               );
             query_posts($args);

		     $home_content = get_option('woo_home_content');
		     $home_boxes = get_option('woo_home_boxes');

			 if (have_posts()) : 

		     $full = FALSE;

		     $width = get_option('woo_full_thumb_width');
		     $height = get_option('woo_full_thumb_height');

		     if( $home_boxes == 'On') { $small = TRUE; }
		     elseif ($home_boxes == 'Off') { $full = TRUE; }
		     else {  $large_posts = intval($home_boxes); }

		     $counter = 0;
			 while (have_posts()) : the_post();
		        $counter++;
		        $post_class = 'full';
		        if( ($counter > $large_posts OR $small == TRUE) AND $full ==  FALSE)
		        {
		            $width = get_option('woo_boxed_thumb_width');
		            $height = get_option('woo_boxed_thumb_height');
		            if( $small == FALSE ) $counter = 1;
		            $small = true;
		                if ($counter%2 == 0 ) { $post_class = 'fr';  }
		                else { $post_class = 'fl'; }
		        }

		     ?>	

 <?php if ( in_category('1') ) { ?>

			<div class="post-outer post <?php echo $post_class; ?>">

			    <div class="post-inner post-alt">
