Does anyone know how to change the point that glRotatef() rotates about (the default being (0.0f,0.0f,0.0f))? -James

glTranslate() before the glRotate() call effectively moves the origin to the specified coordinates.

You can also do the same thing (glTranslate and/or glRotate) using Matrices (glMultMatrix or glLoadMatrix depending on what you are doing).
