I'd second everything Riffs said except the bit about compression: I almost never compress vocals these days, cuz I *want* the dynamic range of the original track. But I go through the vocal track a syllable at a time, and I use a volume envelope to bring down the peaks so that I can raise the volume of the track overall without clipping. Oh - also... before I adjust anything, I often set the volume envelope at - 6 dB. That gives me the ability to either cut the level of a particular sound, OR BOOST IT. More flexibility.
