Hero full screen(only hero module at front),change menu icon

Hey guys, that's my second post, becouse I do not getting any answer...

website: http://demo.macawlab.com/dukes/

I have some questions:

1. How to change aside menu icon ( MENU and triple bar) into a logo image (when clicking on logo image, opens a off-canvas menu)?
2. How to make off-canvas menu items centered?
3. I want to remove copyrights position at all, leave only a header, that it should be in full screen on a frontpage ( no scrolling down or up)?

Thanks in advance!
