Hi Maxbox
I can answer some of your questions, as a distributor for NP for Mexico/Latin America...
1.- Normally, delivery is about 2 weeks, sometimes they can get it out sooner, but that is the average.
2.- They do have a tutorial for the 3 marker wand, but it is geared more to Tracking tools, but the concepts are the same (unless they've recently come out with something)
3.- There is a very complete set of video tutorials that explain a lot of the steps, from how to setup the cameras to how to export.. you can find them here:

4.- Yes, an 8 camera system will support falling, sitting down, etc, for one actor, but does require some trial and error on where to place markers on the body to best accomplish it (for example, if the actor will fall on his face and chest, move most markers to the back of the legs.. etc) and requires very good calibration and camera setup. For example, when sitting down, best done on a stool with no back, a box, etc.. you have to use props that will allow the cameras to see thru them.
Let me know if you have any questions!
