I don't know about the amp part... but I do know that you probably want to keep it at 150deg/s. Yea, in a normal turn you may never go over 80deg/s and you'll be fine... but say, for example, a robot hits you and it jolts quickly. You now are off by a few degrees if you use a smaller range cause it went over your maximum view. Then with movements over a few feet you can definitly be far enough off from whatever task you are trying to accomplish that it isn't performed properly. However, I guess this can vary depending on how easily the robot is spun. Amplifying it to go from 0-5v could be useful though, but I think in nearly all cases you don't want to make the spectrum wider and have to worry about a jolt turning you further than the sensor measures.
