At :17, I think that's Video Co-Pilot Twitch. It's a plugin from Andrew Kramer. I could be wrong though. If that's Twitch, it's set really low, but that's still my best guess. Of course you can do this without a plugin, but I can't tell you how.
As for the other one, aren't they just moving the camera quickly through 3D space?
I'm by no means an AE expert. I'm sure you'll get a better answer from one of the experts.
