Sweet Jebus, man. Why in the *world* would you need all that?

function add_product_var($public_query_vars) {
    $public_query_vars[] = 'product';
    return $public_query_vars;
}
add_filter('query_vars', 'add_product_var');

function do_product_rewrite() {
    add_rewrite_rule('product/([^/]+)/?$',
"index.php?product={$matches[1]}",'top');
}
add_action('init', 'do_product_rewrite');

Then in your template_redirect hooked function, you can do
get_query_var('product') to get the value of your product variable and
act accordingly.

Unless you're doing something completely absurd, I have no idea why
you need all those hooks. Heck, all the posts_* hooks your using have
absolutely nothing to do with rewriting or routing of the resulting
page. Those modify the WP_Query only.
