1) Can't really estimate this, as it is entirely based on how do it. But, If you went with the Kit frame, AndyMark wheels and either dewalt/banebots/AM gearboxes it can probably be done for less than $800.

2) So significant that you would only have a chance at pushing other holomonic robots with omniwheels.

3) advantages; easier on the driver
disadvantages; coding, gyro drift can put it out of alignment, and you need something to originally align it.

4) Entirely based on the game, no way to know for now. But as a reference, for the past few years it probably wasn't the best choice.
