That was a common problem on the first rev of the wheels due to over tightening of the screws that held the sections together, which caused cracking of the plastic. Since then the plastic has been and the torque specs of the bolts was reduced. I didn't hear of anyone breaking them in the 2007 season.
As for the bearing issue, Each wheel needs to have 2 bearings to support it, otherwise your wheel becomes an cantilevered load on your axle creating a moment with the possibility to bend your shaft or the wheel in the worst case. And best case is that your wheel will wobble.
