as above?
what are good lens that can go for low lighting while still maintaining a high shutter.
I heard there is an f1 lens.
How low is your low lighting? If it's very low even f/2.8 won't help, not even f/2.
simple, f/2.8 or wider
IS lens does not affect shutter speed.
not total darkness those kind. cos i was shooting wedding earlier and have to start at 4am when MUA arrived. room lighting is totally cmi, oni a table lamp and bulb was used, no light from outside. so will a 2.8 or 2 work in such situations?
Of course IS affects shutter speed - that's exactly what it's for - to allow you to use lower shutter speeds and still get sharp images than you could otherwise, hand-holding the camera. This is particularly useful in low light as long as the subject matter isn't moving too much for the slow shutter.

I would consider the 50mm f1.8 first or if you can afford it, 50mm f1.4
Fast lens is good for low lighting but not for group shots. For group shots, use external flash and smaller aperture like f5.6 or smaller.
