How can I get my light source to move with the world? It looks really dumb when the light just moves around with the camera.

You need to position your light source after you do your camera transforms, not before.

You can do what Cereal Killah said or you can still do it whenever you want as long as you push the old matrix onto the stack, load the identity matrix, position your lights, then pop off the old matrix, but I would just do it first thing
