I didn't have time to look through those tutorials, but unless something has radically changed in the way AE renders a VR view, two cameras will not do you much good: They will result in a stereo 360 view that is correct only in the front-facing view, flat in the side view (both cameras are in line) and reversed in the back-facing view (left and right eyes reversed to create the exact opposite of a correct perspective correlation for the eyes).

In order to get a proper 360 stereo VR render, you need to render at least 8 or 16 (ideally more) views for each camera with a two-camera rig that is rotatable around the center of the "head", i.e. the center point between the two cameras, render the view as you rotate around 360 degrees in either 8 or 16 steps and blend (stitch) together the center (front-facing) vertical slices of each output for each eye in a separate comp. So that will be 16 or 32 (or more) renders for one output frame.

As for the distance between the two eyes, it is safest to use real-life measurements both in the modeling and the between-cameras distance.
