Gear Ratio to Maximize Chassis Speed?

I would not recommend this, you will notice a significant decrease in acceleration, and your robot will feel sluggish. In addition, you would have to change your gearing or you would likely not be "traction limited". That is to say, when your robot hits a wall or gets in a pushing match, your wheels will not spin.

You might think this is a good thing, but it means that your motors are stalled and drawing maximum current, which will very quickly blow your drivetrain breakers (and could possibly blow your 120A main breaker).
