No.
If you are finding that your legs get so numb that you are unable to stand, you should see a doctor. It is normal to get numb legs from sitting for long periods of time but you should be able to stand up.
Nope. They just pierce it. Anything they could use to numb your lip would cause it to swell up, making it hard to pierce you accurately. Besides, it doesn't hurt very much.

I shoveled snow for so long that my hand feels numb.

Honestly, it should not be necessary to numb the tongue at all to pierce it if you have it done by a licensed piercer. Depending on exactly what you're using to accomplish a temporary local anesthesia, it may complicate matters further. Imagine what sort of damage you'll do to yourself if you get a piece of metal put into your tongue without being able to feel it.
