I agree with Sh@sh and Sunny..
If noise is the problem, lens could not be blamed..
if U were using auto or program mode, probably ISO sets automatically..
So, to control noise, control the ISO.. dont exceed ISO 800 in general case...
Secondly.. 50mm f/1.8 will not perfectly solve the low light shooting issue...
A tripod is must evil.. specially when it comes to low light shoot..
A tripod with kit lens will do solve the problem to good extent..
However, I will stand still with my view of getting a 50mm f/1.8..
just because for the price it comes, you can never wonder of a better deal...
IQ is good, 75mm focal length is decent..
and when it comes to use DOF creatively, the lens evolves out as a boon...
f/1.8 might not perform handsomely in low light, but you cannot get shallow DOF for portraits from any other lens for such low price..

I even had rented the awesome 85mm f/1.2 L II and 24mm f/1.4 L II to cover a night event. 90% of the pictures were hopeless.
I dont think its right to blame 85mm f/1.2L and 24mm f/1.4L...
Coz, you forget that with lower f nummber, the DOF also reduces..
and with f/1.2 it remains to just few centimeters...
also in night, camera often hunt for focus, thus it is no surprise if camera locks a wrong focus..
and with even the minor wrong focusing, the photo will go out of focus at f/1.2
moreover, more the focal length [in case of 85mm] faster the shutter speed you need..
