The Earls Court joke is a reference to the real world. Up until February of this year, The Doctor Who Experience was there (it's now back in Cardiff), so there would've been a TARDIS parked there permanently. For you Americans, the DW Experience is literally a Who museum of sorts - they have all the Doctor's costumes on display, enemies, prosthetics, sometimes people like the guy who plays Strax appear there in full makeup and costume to entertain the kids. There's full versions of the 63, 2005 and 2010 TARDIS sets you can run around and push buttons in and such, a replica of Davros' mothership from Series 4 etc - So the joke is just that they stormed... er, a Doctor Who Exhibition.
Incidentally, every week Cult Box posts (BBC sanctioned) hints for next week's episode. They're very safe hints, fluffy things like "A number one hit from 1981 is heard" and stuff like that. One of those hints for next week is that"Clara makes a reference to Jenna-Louise Coleman."
This is really interesting to me, and potentially related to this DW Experience joke and the whole 'Doctor Who' angle. I imagine the Earls Court reference was just a fun nod for those in the know, but...Is something really meta about to happen?
I don't think Earls Court was about the exhibition - there is an old police box there: http://londonist.com/2011/07/a-spotters-guide-to-the-tardis-in-london.php
Unrelated note: really liked the title and how it worked. Very clever!
