Personally, I would say don't walk....run away from this as fast as you can. It looks good on the surface, but even with the 300WS unit, you would only get as much as f6 with the light at 10 feet from the subject, far less with the rather smallish soft box added. That depth of field is marginal for a single head or couple, but impossible for a group with heads at different depths to the camera.
This might work well on table top shooting where you have the lights almost on top of the product, but something like the Alien Bees or better yet the higher end White Lightnings would give you far more power to work with. Just remember, you can always power down from an 800 or 1600 WS unit, but you can't power up from a puny one.
Also, that small a soft box would still be pretty harsh for a head shot, much less a group where the light has to be farther away. Remember, the farther away it is, the smaller it is relative to the subject and that means harsher shadows and less light spread or wrap around. Something in the 3x4 foot range is much better and the 4x6 foot units are softer (more delicate light and shadow ratios) yet.
