I think you could do the body in one wrap deformer. and attach the hands, feet and head later as smoothed polys, it will take time to weight the fingers and toes but luckily you can mirror weights.

I think if Stahlbergs confusing you ignore the blend shape part and concentrate on the wrap itself and weighting process for now. Learn that first, its a bit of a pain at first but you'll get into it, I can assure you. As long as you select the wrap and mesh in the right order you should have too many probs.

Have fun dude
