Hi,
1/ That's quite simple, so we don't put it on the docs.
You can go to Customize > Featured Video Background and check options for it there.
For menu hambuger, you can go to Customize > Menu Hambuger Options > and you can see options for menu hambuger there.
Also, you can put widgets above & below the menu on menu hambuger via Appearance > Widgets > "Sidebar Hamburger Widgets Above Menu" & "Sidebar Hamburger Widgets Below Menu"
2/ With a special page, you just can select display one: left or right sidebar or no sidebar. You can't display 2 sidebar left & right on a page at one moment.
Best Regards,
PenciDesign
