"If I purchase these two 400 fixtures what will I be able to do with them? Light my green screen and then use the Arris to light the subject? Or should I buy some additional Kino Flos for the key and backlight? "
Yes, use the arris to light your subject. Or, if you have access to lots of funds, get a Diva 400 for key, and a 200 for backlight. (And a 4x4 sheet of foamcore to bounce fill from the key.) Also, get a few c-stands, a couple of flags, a variety of grip-scrims, and a few sheets of 1/4 CTO (orange), 1/4 CTB (blue) for starters.
Finally, you could also go the classic Kino Flo route, two 4x4s for the green screen, plus another one for key, and a 2x2 for the backlight. Add the c-stands etc.
Note the Diva package you list does NOT seem to include bulbs.
