You have to build the VBO too, but yes, display lists are deprecated.

As far as dynamic stars, yes, the idea is to use either a display list or a
VBO and either transform or use a vertex program to move your stars. For
starfields, I personally have gotten compelling results by simply making
several static starfields of different sizes and then scrolling them with
glTranslatef at different rates. This gives a nice parallax effect, and is
essentially just as fast as drawing the stars completely static.
