| Yes, real-time pitch correction has been available in a hardware version longer than software plugins have been available. Antares, T.C. Helicon, and Eventide all make rackmount vocal processors with pitch correction. Britney Spears tours with 4 Antares Auto-Tuners.
Problem is, they need to be programmed properly, and they're expensive. I'm not sure if they still rely on a melody being preprogrammed or if they automatically detect the proper note yet. Real-time software isn't, really. It adds to your computer's latency, and can look ahead at the signal. The resulting delay is too long for live usage.
All the stuff you listed helps, but really, a good singer through a good microphone is the #1 way to get good vocals live. Practice a lot and take voice lessons. The real "tricks" proffesional singers use can only be taught by a vocal coach working with you one on one, IME.
