Hello, I just had my interview last week and this is what my instructions said about registering at TNT: choose CR-1 instead of K1, so this way they will not ask for a receipt number.
Then simply print confirmation page, they will ask for it at the interview (and they wont return it to you, btw).
You will need your ID (buletin) to go and pick up ypur passport.
You will indeed pay the 240$ fee at the consulate, after you present paperwork and before they take your prints.
Good luck
