How to Change BP Scholar home page layout

Please see the image of the Scholar Home Page.

1. How can I change the Home Page to use or look like the Right Sidebar Template?

2. How can I find, save and reuse the shown Left Sidebar Widgets "Search our community" and "Follow Us" so I can add them to the Right Sidebar?

3. How can I remove the Left Column so the Home Page looks like the Right Sidebar Template but retains all the other features of the present Home Page?
