(SPOILER)I also found that age numbers were missing from her book. I knew 23 was missing, I didn't give a hard enough look for the other numbers. It's interesting why their missing.

As for the lady in the shop? Hmm. Might be River Song. That was my first guess. It's going to be a friend of the Doctor I think. It can't be Amy or Rory given they were sent way back in time. Could be Martha I suppose, I mean, she's not dead or otherwise been teleported off somewhere. I can't think of any other ladies to be fair.
