Custom query pagination sort order with jquery.

Trying to create a custom query that uses jquery to update
pagination/sort order. Please help me a little. Im just a little confused at this point on how to do it with wordpress.

I need pagination that updates with jquery/ajax (so the page dosnt reload)

And the same for sort order drop down boxes.

<div id="offers" class="tabs-container" style="float:left;">
<ul class="dsblisting">
<?php query_posts($query_string . '&cat=8'); ?>
<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<li class="clearfix offer">
		           	<a href="goOffer?1745732" target="_blank" class="item" onclick="piwikTracker.trackGoal(1); return true;">
		              <div class="image-container">
		              		<?php
							 $mykey_values = get_post_custom_values('image');
  							 foreach ( $mykey_values as $key => $image )?>
 							 <img src="<?php echo $image ?>">
		              </div>
		              <div class="content">
		                <h6><?php
  							$mykey_values = get_post_custom_values('title');
  							foreach ( $mykey_values as $key => $title )?>
  							<?php echo $title ?></h6>
                        <p>
                        <?php
 						 $mykey_values = get_post_custom_values('description');
					     foreach ( $mykey_values as $key => $description )?>
    					 <?php echo $description ?></p>
                        </div>
                        </a>

		            </li>
                    <?php endwhile; // end of the loop. ?>

</ul>
</div>
