Hi Sean and Carlos,
I followed Wim's tutorial (see my earlier message) and my results looked
great on Oculus Rift. As for the number of images the workflow reminded
me of the ObjectVR shots I did around 1997: for me 36 images are a good
number of frames to process. With 36 steps for one panorama you want to
avoid moving objects though.
In this case I used my circular fisheye (the 2.8/8mm Nikkor) on a full
frame camera, a sturdy tripod and my rock solid panoramic head which has
a 10 deg. setting. No bracketing, just 36 RAW images which took me
exactly 1 min 30 sec to shoot (including two frames I shot twice).
Stitching images with such a vast amount of overlap works like a charm,
even with the parallax "errors" I had provoked.

The advice from that forum post in the other reply seems to be pretty
good. Keep the number of photos as low as possible to keep the number of
seams down, and avoid very close objects to the camera (which cause the
most severe parallax).
I haven't done 3D panoramas yet, but from what I've read it looks like
you can't do a few number of images. 12 looks ok, as I've already read
that 20 would be a good number. There was a post at facebook where
people discussed the small number possible. Nobody was able to do with 4
and the results were improved when increasing the number.
Maybe some device like this -

- can reduce the shots in half.
