Change advanced menu structure on Wordpress page, make mobile page and copy and alter 5 templates to create 5 new ones

All of this has to be implemented using best-practices for Wordpress. NO custom hacking or PHP re-encoding unless checked in advanced! Currently, a wordpress site has the same kind of left hand menu as this site: [login to view URL] But we'd like to have a new menu-structure implemented so it has Menu1, 2 and 3 items like: [login to view URL] (A document on what current item goes where is available). On top of this, the new site should also have a mobile site implemented, such that the mobile tagged pages will show up also in a mobile specific site. Lastly, 5 template pages (that already exist) need to be modified somewhat concerning placing of widgets, width etc, such that 5 new ones are created.
