Dear Dymitr, 

ad 1.: YES

ad 2.: YES

ad 3.: we do not compensate gravitational force from raw readings, so -9m/s2 sound more or less right for non-movement (z-axis pointed downard). Please note that fast movemt of feet for example can easily achive 160 m/s2.
As for oscilation around zero... we were looking into the data very closely before opening them into competiotion and I woudn't say that acceleration oscilates around 0 (maybe you are looking into gyroscopes?)
