The answer to the first question can be found in section 2 (Building C
and C++ Extensions on Unix) of "Extending and Embedding the Python
Interpreter", available at www.python.org and many other places that
have the standard Python documentation. Assuming of course that you
are using Unix, for other systems the procedure is different and
probably compiler dependent.

As for the second question, the simplest solution is a test import:

  try:
     from foo import bar
  except ImportError:
     print "Sorry, module 'foo' is not available."
