BP Scholar Layout Question

Hi

I've installed this theme & wanted to know how to do the following:

1. The home page is 3 column layout, but the page and post is 2 column layout. Can the page and post also be a 3 column layout?

2. The post has content on the right, sidebars on the left side. Can this be changed so that the sidebars appear on the right side?

3. Is it possible for a page to have a different layout from another page (e.g Page1 is 3 column, Page2 is 2 column?)

4. The Follow Me/Social Media box - how does one change the icons (e.g I want to have Linkedin URL instead of YouTube)
