wordpress - wordpress onclick AJAX load specific post type with specific custom field

Question

it's my first post here on stackoverflow after finding help for tons of questions- Thank you so far.

I'm building a wordpresstheme within Wordpress 3.0.4.

Theres's a navigation: Home | comedy | scifi | action | arthouse

I have set up some custom post types like "reviews".

Taxonomy = films

slugs = comedy, scifi, action, arthouse

I also added the possibility to acitivate a custom field "feature" inside every post.

On the front end startpage all posts from custom post type "reviews" are shown.

Now theres a button "featured" - when see visitor clicks that button, only posts with customfield "featured" shall be shown.

The content should be loaded with AJAX.

I know how to load stuff with AJAX from another page inside wordpress.

E.g.: I'm using:

    <script type="text/javascript">
    $(document).ready(function(){
    $.ajaxSetup({cache:false});
    $("#featured a").click(function(){

        var post_id = $(this).attr("rel")
        $(".wrapper").html("loading...");
        $(".wrapper").load(jQuery(this).attr("href") + " .wrapper")
        return false;
    });
});
</script>

so when someone click the button "featured" ajax loads a .wrapper part from another page:

<?php 
 query_posts( array( 
    'post_type' => 'reviews',
    'taxonomy'  => 'films',

    'meta_key' => 'featured', 
    'meta_value' => 'yes', 
    'posts_per_page' => 10 
  )); 
?>

so the query is kind of "fake filtered". But that only works for one slug/category e.g. "arthouse" not dynamically.

When the visitor goes to a specific page e.g. "arthouse" - only posts of custom post type films are shown with slug "arthouse".

Using this query:

<?php query_posts('films=arthouse'); ?>

Now the question: How can I get wordpress to understand, that "onclick" the featured button only the posts with "featured" = "yes" are shown inside the slug "arthouse"?

Is there some js filter I could use? GET handler? Or what would be the right way?

I really appreciate some help!

thank you!

But how can I make something happen with just a click?

Is there a way to let jquery handle a php query?

I know how to query posts with more than one taxonomy like in this post here: https://wordpress.stackexchange.com/questions/7107/how-to-filter-custom-posts-by-tags-and-custom-fields

but how can I do it with ajax - without a pagereload? Like this somehow:
