Want to Display All Categorys on a Page in Wordpress with Image, Title, Description, Link

I have been trying for a couple of days to make this function work on a website we are building, but it is totally frustrating me.

Basically i want a page on wordpress, which has a list of all the category's on the website, with an image, title, description...  much like a standard blog post would be displayed (title,image,excerpt,read-more).

I found the plugin "category-icons" found here Which lets you assign an icon/image to a category.  I have been trying to modify the function they suggested though, so i can display the Description, aswell.

Here is the Category page  webpage

<?php
add_shortcode('caticons_listing2','bm_caticons_listing');
function bm_caticons_listing() {
    $listing_code = '';
    foreach(get_categories("orderby=name&order=ASC&exclude=33") as $category) {
		$listing_code .= '<div class="et_pt_blogentry clearfix">' ;
       	$listing_code .= ''.get_cat_icon("echo=false&cat=".$category->cat_ID).'';
		$listing_code .= '<h2 class="et_pt_title">'.$category->cat_name.'</h2><span class="category-description">'.$category->description.'</span>';
		$listing_code .= '</div>' ;                      	
    }
    $listing_code .= '';
    return $listing_code;
}
?>

I'm getting the image, title, and description to display, but only the image links to the actual category. How can add the link to the title also, and if i add a read-more button after the description, that links to the category also.
