If you don't know R already, then you should work your way at least through
parts of some R tutorials, there are many but I don't have any
recommendation.
It's also possible to work through Rpy2 and look at ipython notebooks that
use Rpy.

For comparison with scipy.stats you mainly need simple functions, so you
don't need to know a lot of the "more complicated" things in R.

What I usually do is to search with Google or in R help for the name of a
hypothesis test, for example, and then run a simple example both in R and
in python and compare the results. If the results differ, then we need to
check whether the R and python versions use the same options. algorithm or
assumptions.
At the current state of scipy.stats it is now unlikely that the difference
is just a bug (except maybe in some corner cases).
