how to solve this jquery problem

Hi, I have page with jQuery  click here to see   code for this site is
  2. <script type=""  src="http://code.jquery.com/jquery-1.5.js" ></script>
  3.   <script type="text/javascript">
  4.       var delay = 4000; // you can change it
  5.       var count = 5; // How much items to animate
  6.       var showing = 3; //How much items to show at a time
  7.       var i = 0;
  8.       function move(i) {
  9.         return function() {
  10.           $('#feed'+i).remove().css('display', 'none').prependTo('#feeds');
  11.         }
  12.       }
  13.       function shift() {
  14.         var toShow = (i + showing) % count;
  15.         $('#feed'+toShow).slideDown(1000, move(i));
  16.         $('#feed'+i).slideUp(1000, move(i));
  17.         i = (i + 1) % count;
  18.         setTimeout('shift()', delay);
  19.       }
  20.       $(document).ready(function() {
  21.         setTimeout('shift()', delay);
  22.       });
  23.   </script>
  24.     </head>
  25. <body>


  28.     <div id="container">
  29.         <!-- Header Logo -->
  30.             <div class="slider"><div class="arrival_button">Wait for just 4 seconds...!</div>
  31.             <div class="sliding"><div id="feeds">
  32.                     <div class="item" id="feed0"  style="display: none;"><div class="thumbnail"><img alt="image"  src="http://www.flashdaweb.com/blog/wp-content/uploads/2008/10/website_development_program.jpg" width="125" height="100"></div><div class="info">hello this is me</div></div>
  33.                     <div class="item2" id="feed1" style="display: none;"><div class="thumbnail1"><img alt="image"  src="http://www.esellswebdesign.com/wp-content/uploads/2008/08/designing-a-fast-loading-website.jpg" width="125" height="100"></div><div class="info1">hello </div></div>
Now come towards the problems. I'm new to  jQuery thats why my question might be stupid. 
1: When the page load why it takes so much time to start sliding.
2:After sliding is completed it starts in reverse order i.e its slide up in the end i comment
$('#feed'+i).slideUp(1000, move(i));
this line but then the slide will stop when it completed. so is there a way to continously start the slide in slidedown direction.
