As I understand it the OP is having trouble with "dreaded orange glow" and not his shutter speed - so new lenses are really fun but they won't do anything about your problem. Most cameras have the ability to register an image for custom white balance. It is the white balance setting that has this symbol
Find something white to take a picture of and then learn how to use this function on your camera and it should solve your "orange" problem.
Also - no cameras do a perfect job of AWB in any indoor or outdoor environment. Its nice that the newer cameras do better than the older cameras... but they are usually still off by quite a bit if you are actually worried about having nice looking skin tones. Outdoors, most cameras will balance too cool while indoors they tend to be too warm.
If you are shooting under sodium lights then slower shutter speeds will actually help your white balance because the lights can go through a whole cycle while the shutter is open. Under regular tungsten or florescent you should not have any complications unless you have mixed lighting with an open window nearby.
