"You look Time Lord."

That other person is right - it is messy, and it's not easy, but you CAN learn it with a few basic instructions. Though, I will submit that Rory didn't REALLY instruct Amy beyond "just like telly" which IS a load a crap.

3) I'm glad he went into such detail, because I just kind of was all... "There's so much wrong with this, I don't even know where to start, so I'll just brush it off as horrible TV CPR."

4) Being in the military doesn't mean you have knowledge of sailing though. And it all depends on perception. The difference is: Everyone else was so baffled by "bigger on the inside" and trying to sort that out in their heads, that they didn't really LOOK at the controls or what the Doctor was doing. Avery DID. He noticed what the Doctor was doing and in his head, was able to piece it together. I don't know... I was able to buy it - at least more than Amy sword fighting or the CPR bit. But it's my small gem in an episode that I enjoyed until I thought about it, so maybe I'm just not willing to go there :P
