Wall board screws. They have a course thread and a flat head.

No, this unit may only be hung on a wood stud, concrete, or cinder block.
The box must be securely mounted. In some applications "Old Work" boxes are made to be secured by the sheetrock.
yes, that's how I discovered mine. Sheetrock has paper on both sides. Paper is made from WOOD.
Sheetrock or drywall should never be used as part of a door. It is just not durable enough.
Sheet rock screws. Alternative: If you have a hole in your ceiling and want to fix it you use a piece of wood to hold a piece of Sheetrock which you will finish with plaster or joint compound. You would cut a piece of wood more narrow than the hole and longer than the hole. Put the wood into the hole so it cannot fall out. Cut a piece of Sheetrock to about match the hole and screw the new piece of Sheetrock to the wood. Use joint compound to give the repair a finished look. If you simply put joint compound into the hole it will crack and take many coats. Paint.
If you are looking for a stud, you could tap (hollow sound means no stud), check for nails in windows or trim (usually nailed to a stud), or use a stud finder.

You'd likely want to have a stud finder if you can't find them manually.You'll want to put two wood anchors securely into two studs and secure the mirror by these.
