Normally a circular fisheye with 3 or 4 shots plus eventually zenith
and nadir or a full frame fisheye with 6 to 8 shots + zenith and
nadir.

Some people do, most don't.

If you use PTGui for panotools you can easily try it out. Simply take
any image, load it multiple times, set input field of view to the
value of your lens and move the images around in panorama editor
until you have arranged them with enough overlap. In Image Parameters
tab you can read the Yaw and Pitch values...

A good starting point is the panotools wiki:

The WWP list was dedicated to announcement and discussion of the WWP
events.
