It has always had the holo recording system it is usually used by the Doctor to leave messages to companions. For some reason the TARDIS felt it had to talk to Clara, which is important in answering the question about her. For starters this version of Clara "Oswin" Oswald is her first life, it is made clear she started out just a normal normally intelligent girl, thanks to some melding by bad guys her intelligence is raised, as she travels she is slowly changing next episode she will be exposed to the Heart of the TARDIS, ie the strange thing that happens to her is indirectly/directly the Doctors fault. So yah her difference as a person will come out by the end of next episode.
as to plot holes mentioned, Everything in Doctor Who is a plot hole filled with silliness, the entertainment of the show is not diminished from facts or reason.

I hope not, it is nice to see a strong female character who can get along quit well with out an all important male telling her what to do.

It's all leading up to the Birth of the
Valeyard. The ultimate Doctor Villain, his soul spilt evil twin. At a guess they might have John Hurt play him, or even David Tennant. Which would be awesome.

Since the classic show is a much slower paced show Start with the 9th Doctor aka 2005 Doctor Who, however at some point after you become addicted and feel like you can handle the much slower pace of 60's, 70's and 80's British TV get a hold of the classic show, however be aware many episodes of the 1st and 2nd Doctor are missing. Sadly the BBC destroyed a bunch of the early stuff, not realizing the cultural value of the show.
