You have to buy the tickets for the Nordschleife in advance, I'm pretty sure that there is no option to pay on location. You can buy them on the official Rock am Ring website (Tickets -> Nordschleifenticket).
On the Nordschleife there are no regular showers, but you can use the ones on the campsites nearby. It depends on where your camp on the Nordschleife is, but that could be a long walk if you are not next to Schwalbenschwanz or Campsite A2 (Tiergarten).
Also keep in mind that the Nordschleife will be opening on Thursday only at around 10am. They will definately not let you enter it before the official opening.
Cheers!
