2. $post = get_post($id);
   $category = $post->$post_category;
   cat_is_ancestor_of(($parent_category, $category));
   

   For more info see the get_post and cat is ancestor of references. Also, while somewhat difficult to find this is a good place to start for most wp development related things.
