According to the datasheet, also S0, S1, Aux_in, PD, ST should be tied to ground if they are not used.

You could tilt the sensor 90 degrees to the right, to the left, forward, backward and upside down. Do the values change ?

You could use the on-chip multiplexer if you are running short of analog pins - 2 digital pins to S0 and S1 enable you to route x,y or z to the Vmux pin - so only one analog pin then needed.  That or just use 3 analog inputs for x,y,z.

Yes its very similar to the ADXL335 except that the sensitivity is 660mV/g instead of 330mV/g  (that's at 3.3V - it will be 1V/g at 5V supply since its ratiometric).

The range of the output is from 200 to 600 in 3.3v, is that ok? If it is ok i have 1 problem. The smoothing :) of the ouput.
