Answer to Question 1

They formed early, while the protogalaxy was spinning slowly and was roughly spherical. Over time, rotation flattened most of the material into a disk and formed the Population I stars later.

Answer to Question 2

It is not just us, but everyone, everywhere who witnesses the same cosmological redshift, as all space and time expand in the Big Bang. Since space itself is expanding, there is no preferred direction and no center to the universe.
