I agree with what has been said already.
White Balance is just a matter of colors with digital. It used to be important when you didn't have the freedom to change colors after the click, nowadays you can pretty much change everything with a single curve control, so it's just about your preferences in how the image should look.
It still has applications, though, if used with a proper reference, a macbeth checker or a proper grey card, and speeds up the work a lot in controlled lighting environment.
If you don't have a controlled environment probably white balance doesn't need to be accurate (in the sense that the colors you'll see on your screen should match the ones your eyes were looking at when shooting), and you can pretty much do all the color corrections you want or need.
Even a skin-tone can be quite arbitrary (in a certain range), sometimes a grey card helps to set a tone color standard to which everybody must agree without too much discussing
In the movie industry, for example, the White Balance is totally ignored these days, because everybody shoots RAW so everything can be changed later, but a macbeth chart is always shot as reference, since all the cuts needs to be consistent and the only way is to refer to the proper color chart.
