    o  Is there a difference between inertial mass and gravitational

       difference between the effects of gravity and the effects
       of being in an accellerating frame of reference?" But
       Im sure Im making a drastic generalization.)

No difference.

    o  Given the old "accellerating-elevator-in-space" experiment,
       how can one within the elevator tell the whether he is
       accellerating or under the influence of gravity?

You can't tell the difference.  This is the heart of general
relativity.
