jQuery conflict in wordpress header - help!

Just posted this in the wordpress forum and realized it’s probably better suited for here. Apologies for the double post (how do I delete the other one?)

I’m having some trouble with three jQuery parts of my site header. I am trying to get a jQuery dropdown menu, photo slider, and colorbox to all work on the same page. I have some sort of conflict going on and not all three seem to work at the same time. I’m guessing it’s a conflict of jQuery loading differently for each item, possibly as well as the jquery library being loaded by WordPress in the functions.php page.

I can’t figure this out. Anyone want to take a look and let me know what you think?

Here’s the header:

<head>
	
	<title>
		   <?php
		      if (function_exists('is_tag') && is_tag()) {
		         single_tag_title("Tag Archive for &quot;"); echo '&quot; - '; }
		      elseif (is_archive()) {
		         wp_title(''); echo ' Archive - '; }
		      elseif (is_search()) {
		         echo 'Search for &quot;'.wp_specialchars($s).'&quot; - '; }
		      elseif (!(is_404()) && (is_single()) || (is_page())) {
		         wp_title(''); echo ' - '; }
		      elseif (is_404()) {
		         echo 'Not Found - '; }
		      if (is_home()) {
		         bloginfo('name'); echo ' - '; bloginfo('description'); }
		      else {
		          bloginfo('name'); }
		      if ($paged>1) {
		         echo ' - page '. $paged; }
		   ?>
	</title>
	
<?php if ( is_singular() ) wp_enqueue_script('comment-reply'); ?>

<?php wp_head(); ?>

	<script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/jquery.min.js"></script>
	<script src="<?php bloginfo('template_directory'); ?>/js/dropmenu.js" type="text/javascript"></script>	
	<script type="text/javascript"> 
	jQuery(document).ready(function($){
	    $("#nav-one").dropmenu();
	});
	</script>
	
<script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/jquery.easing.1.3.js"></script>
<script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/jquery.DDSlider.min.js"></script>
<script type="text/javascript">
	$(document).ready(function() {     
            $('#yourSliderId').DDSlider({	
				nextSlide: '.slider_arrow_right',
				prevSlide: '.slider_arrow_left',
				selector: '.slider_selector'
				});     
});</script>

<script src="<?php bloginfo('template_directory'); ?>/colorbox/jquery.colorbox.js"></script>
<link media="screen" rel="stylesheet" href="<?php bloginfo('template_directory'); ?>/colorbox/colorbox.css" />
	<script>
		$(document).ready(function(){
			$(".example5").colorbox();
			$(".vimeo").colorbox({iframe:true, scrolling:false, width:700, height:440});
		});
	</script>
	
	<link rel="shortcut icon" href="/favicon.ico">
	
	<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>">
	
	<link rel="pingback" href="<?php bloginfo('pingback_url'); ?>">
	
</head>

I’m also using this in the functions.php doc:

	// jQuery inclusion	
	if (!is_admin()) {
		wp_deregister_script('jquery');
		wp_register_script('jquery', ("http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"), false);
		wp_enqueue_script('jquery');
	}

Any help is much appreciated. I’m stumped here.
