The first of the series was a sequel to The Girl In The Fireplace -- didn't you catch when he specifically mentioned the ship Madame de Pompadour, near the end?
As for the dalek, when they said they found it just floating, broken, through space, my first thought was that it was Oswin -- Clara, from the asylum. Impossible girl, after all. *shrug* Different ending, too.
And, no, I didn't notice that he's like Tenant's Doctor, probably because there's supposed to be a bit of similarity (considering they're, y'know, the same person in the first place), and "a bit" is all there really is, as far as I can tell.
