Yes it's required and no there's no way to avoid.

Oh, I just realized what your problem is. You haven't uploaded the config into the device. On every boot you need to upload the full 8KB config file into the device as that's the microcode for the sensor. It won't do anything without it.

Well first your logic is incorrect. The data order is LSB then MSB so this is wrong: response = Wire.read()<<8|Wire.read(); Also realize that you're reading the X axis which would basically be 0 if the device was sitting level on the table. Try reading the Z axis and you should get about 1G.

I haven't tried reading only the LSB. Try reading both the LSB and MSB. Reading only the LSB might be preventing the register from getting updated. From the datasheet: Reading the acceleration data registers shall always start with the LSB part. In order to ensure the integrity of the acceleration data, the content of an MSB register is locked by reading the corresponding LSB register (shadowing procedure).

See page 60 of the datasheet and the GYR_RANGE register. The default is 2000dps. Yes, 2000dps is 2000 degrees per second. Gyro samples show rate of rotation, not acceleration.
