As far as I can recall, Kolmogorov-Smirnov test (Stata: ksmirnov) is
the uniformly most powerful test for comparison of an empirical to
fully known theoretical distributions, if there is no need to estimate
the parameters of the latter. It cannot answer your second question
though; it just says if the difference between the two distributions
is within the limits of sampling fluctuations.
