Hi Allesandro,
There's no need to redirect home button to the other page to swap the frontpage with static page. You can go to the WordPress admin dashboard > Settings > Reading and change the 'Front page displays' to : 'A static page (select below) ' and choose the Page for your Front page. This will make the home button to work like a link to the chosen page.
In case you'd like to exclude a page from the menu please open header.php from your theme directory, find this code :$my_pages = wp_list_pages('echo=0&title_li=&link_before=<span>&link_after=</span>');
and replace it with this one :$my_pages = wp_list_pages('echo=0&title_li=&link_before=<span>&link_after=</span>&exclude=ID');
where the ID is the Page ID of the page that you wish to exclude.
