Hi, I quite like the site and it's easy to follow.
I would recommend trying to emphasise the links on the left-hand menu.
Also, I would change the "ENGLISH" link to a British flag as this be more catching. Once you are on the English page, I can't see a link at the top back to the Italian site. Maybe you could add the 2 flags side by side.
Nice website, its good use divs instead of tables, this is good for SEO.
About the first H1, if you use it with less words, you can maximice your results to it word because a use of a lot of words decrease the wheigt of every keyword.
