If you swipe down from the status bar (swipe down with finger from very top edge of screen down when on main menu) it brings up the "do not disturb" on/off toggle that looks like a circle with a dash inside of it with a diagonal slash through it.
You can also re-arrange these "tiles" by touching on edit once you expand these status bar notifications/quick settings options.
As far as a shortcut to the volumes, if you press volume keys when on the main home-screen you can change these quite quickly with access to sliders for media, ringtones, notifications etc...
