Please help me specify the following Predator components

Friends:

I would like to buy the components for a Predator Sumo including all electronics, but I need a little help.
I have experience with the Parallax Boe Bot and Sumo Bots and would like to go to the next level.

Can you help me specify the following:

Predator Sumo # GHM-03 7.2vdc 30:1 - 36.0" per Second
Sumo Tire Upgrade Predator
Motor controller(s) … which, how many do I need? Which do you suggest?
Mini Atom Bot Board
Basic Atom Pro 28 Pin for Mini Atom Bot Board
Battery Pack(s) … which, how many do I need?
Edge Detectors front and rear … which, how many do I need?
Opponent Detectors … which, how many do I need? I want to see in all directions.
Cables?
Accessories?
Anything Else?

Thanks in advance,

Miguel Reznicek
