Hey Will,
As much as we want to assist you here, this is way beyond the scope of our support. As Arlex has already provided you the guide, that is the best we can do since this is totally unrelated to our products.
Anyway, I have helped you to setup the "Italian" menu on your site and you should use this as a sample to re-create the respective menu for the rest of the languages. You are only missing the menus from the site.
