I can answer the Richter question.
Basically, while working out a deal for her contract, there were disputes between McMahon and Richter about things like Royalties for the cartoon and such.
Richter was scheduled to defend her title in Madison Square Garden against THe Spider Lady, who was played by various wrestlers over the years. In this case it was Moolah.
Moments into the match, the referee did a fast count, and the bell rang...which Richter didn't know about. She unmasked Moolah afterwards. Richter never returned to WWF.
