the camera move through 3d space focusing on various imagery is pretty basic AE 3d space camera moves. It involves placing imagery in a staggered way which simply involves entering coordinates and getting comfortable with xy and z spacing.
The second effect may have been done in a 3d app. My hunch is it may have been all AE. And with some custom scripts is my guess as well.
To do it by hand would take forever.
As for tutorials, I have not searched for any on these topics. I figure most people come here after looking for tutorials first.
good luck..
