You might not want your landing page to contain all the content that it has by default. If you look at the landing.php template you will see that it's easy to exclude different sections, even to take all the content out of it so that it is just a splash page.
If you want to use some of the sections elsewhere you can make custom templates easily. Here I have taken the template nosidebar.php and added the Call-to-Action include under the main content. Just copy and paste.
