1) autofocus performance in night depends mainly on your camera, but the f2.8 will focus better than an f4 or f5.6 lens

2) if you are shooting at true life-size macro for static objects you would normally need a tripod and patience to compose the shot so the OS does not seem a key feature. If you can manage to get close to live bugs at near life magnification you might want OS.
