That's pretty much the way it is around here in my part of Texas. I say "you" for singular and "y'all" for plural.

Father Bill's slight dig notwithstanding, "y'all" is perfectly good English. It's just a contraction for "you all". If you would say something like "How are you all doing today?" to a group of people, I see no rule against using a contraction in the form of "How are y'all doing today?". If "y'all" is not proper English, then neither is "I'd" or "I'll" or "you'll", etc.
