IMO, use audacity alone is enough, I myself use only audacity and I can reduce the noise into minimal. Still if you want a perfect, no noise record, you would need a sound proof room or at least a mic with voice filter (Is it what they call it? The little grid thing put in front of the mic to filter the voice?)

If you stuck with audacity, just use Noise reduction 2 or 3 times, after that cut out unnecessary parts (the parts where you don't sing) that have noise in it, then your vocal would become... cleaner? I guess...
