re: Soaking red beans...

Your soak time should be fine. Also, I was once told by an old-timer (a great cook)that adding a table spoon or two of baking soda to the beans while boiling will tend to de-gas them somewhat.

I've tried it and it sure does make a huge fizz and foam when you put it in (and doesn't change the flavor). As to the level of de-gas......i'm not sure.
