Is the Perspective matrice set when the gluPerspective is called? does it remain the same the rest of the time if you are working with the MODELVIEW matrix? I am trying to minimize the amount of glGet* calls

The projection matrix is not set, but rather multiplied with the currently activated matrix stack. If you want to 'set' the projection matrix, you have to do the following:



glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(...);

And it will remain the same when working with the modelview matrix.
