About the ADXL50 accelerometer's resoloution:

Full scale is -50g to 50g so that's (about) 100g Full Scale (FS)
FS output span 0.8 to 2.8 Volts
Zero-g output 1.80 Volts
Sensitivity 20 mV/g (Milivolts per g)
Voltage Noise:
  At bandwidth = 0.3 kHz  +/- 0.33 %FS  (I think this is +/- 0.33g)
  At bandwidth = 1.0kHz  +/- 0.6   %FS  (I think this is +/- 0.6g)

So I don't think the resolution is really great but I don't have a good
idea of the accelerations you might want to measure.
