Questions about Roasting Shelled Peanuts -

1. Is there a non-tedious way to remove the peanut skins?
2. My salt isn't sticking to the peanuts (I grind salt over the peanuts just after taking the tray out of the oven) - what should I do differently?
3. Do I need to use parchment paper, or can I roast peanuts directly on the baking sheet?
Thanks :-)!!!
