1. We can tell this is the Apollo 11 set because of the American flag and the overall set up looking similar to that of the scene that was televised. This isn't the Soviets' work.

2. I'll keep my eye out for more references to the necklace, but the reason Mrs. F walked out in the B&B scene was because she had business to do with Leena. The writers kew the audience would question why she'd walk out on her own instead of teleporting, so they added in a small reason so it would make sense so that it would make a bigger impact when she really couldn't teleport with Parry in power. The limited number of "pops", as brought up by one of the other people in that episode's commentary, would according to him make the necklace shorter each time it is used. Whether it can replenish itself in some fashion was never mentioned, but I'm thinking that aspect was never further considered by Jack.

3. I know extremely little about Norse mythology so I wouldn't know any potential connections pearls have with the tree. I can't remember if Parry teleported when facing Claudia, but since he walked to the Office, we can assume he might not be able to (Mrs. F was, in Abigail's debut episode, seemingly able to teleport herself /and/ Abi into Artie's office). However, if he did teleport, then that's even more complicated. The necklace changing forms is a bit less likely even if it would make sense because, even though we have plenty of canon and Database artifacts with multiple effects that are pretty different, I feel like it would be a stretch.
