1) and 2) are hardware dependent. If you need something with higher acceleration range than standard handsets, you'd probably have to have it built. Accelerometer - chips are made to many different specs, but generally, the higher sensitivity, the lower the range. Remember also that there can be both "Acceleration" and "Gravity" sensors on android devices, one measures zero acceleration when lying still, one measures 1G (~ +9.81m/s^2) when lying still. The update-speed is also determined by the specific device. 3) An accelerometer is probably not a good way to detect a "golf-swing" - at least not alone. Acc-sensors measure linear accelerations. If you combine it with a gyroscope-sensor you could test for a simultaneous "rotation and high-G" type of movement. Otherwise it would be difficult to determine if the user is merely shaking his phone... Also be aware that even a just couple of G's are quite a bit! - Android devices are really meant to be weaponized - not yet at least...
