Wouldn't that be superfluously fast? With 300 deg/sec over a range of 1024, which is truncated to 512 because of a direction, you end up with 300 deg / 512 values = around .6 degrees per increment. If you're going at the maximum rate, of 300 deg/sec, going .6 degrees will take you .6/300 = .002 of a second to go one tick. That means that hypothetically, querying at 500hz (1/.002) will be enough. And that's if you care about the tiniest turn. However, that might not work anyway, due to the fact that ADC conversions have noise.
The reset button sounds like a great idea and something we'll probably implement if we find ourselves using a gyro during the user controlled mode (which is not a given seeing as we are not building a holonomic drive train).
We'll probably implement a gyro on our robot this year to help with accurate turning, especially during hybrid.
