Problem with showing one category on homepage

Having problems with limiting the home page to a single category. My page shows excerpts of all the recent ones in a specfic category but the whole post of the most recent one, regardless of what the category is.

Here’s the relevant bit of code…

<div class="top_Post">

		   <?php $sticky_counter = 0; ?>
			<?php query_posts('cat=6'); ?>
			<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
				<?php if ( is_sticky() ) { ?>
					<?php $sticky_counter++; ?>
					<div id="" class="l_post">
					  <?php if(get_settings('kasrod_color')<>'') { $background = get_settings('kasrod_color'); } ?>

					  <div class="post" id="post-<?php the_ID(); ?>">
					  <h3 class="title" style="background:#<?php echo $background;?>; border-bottom:solid 1px #<?php echo $background;?>; "><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h3>
					  </div>
						<p>Written by: <?php the_author_posts_link(); ?> on <?php the_date(); ?> @ <?php the_time(); ?></p>

					  <?php //the_content('Read more');
						the_content();
					  ?>
					  <?php wp_link_pages(); ?>
					  <?php the_tags( '<p>Tags: ', ', ', '</p>'); ?>
				Catogories: <?php the_category( ', '); ?>
						<br/>
					  <?php edit_post_link(); ?>
					  <a class="more-link" href="<?php the_permalink() ?>" rel="bookmark" style="color:#<?php echo $background;?>;"
						title="Permanent Link to <?php the_title_attribute(); ?>">Read more</a>
					</div>
				<?php } ?>
			<?php endwhile;
				if( $sticky_counter == 0 )
				{
			?>
			<p><?php wp_last_posts(1); }?></p>
			<?php endif; ?>

           </div>

Have got the <?php query_posts('cat=6'); ?> in the wrong place?
