Did you try to read the gyro using sample code or your code? I like to use the sample code first to eliminate possibility of software problem. Base on the random readings, I would also verify wired correctly. Could just be seeing electrical noise.

As to if the gyro is to fast. It can never be fast enough! Seriously, this is just the frequency response of the sensor. The higher the value, just means it is capable of responding to faster turn rates. Has nothing really to do with the software reading it.
