Optimum calibration settings for uMB with 9C89 screen

I have tried calibrating the LCD screen on my macbook and after calibration the screen looks much better than it has before. The whites "pop" out more than they used to. The one thing I am noticing though is that some black text that I am seeing is looking to have more of a brown tint to it. Is there an optimum setting for calibration on a uMB so the colors look the best possible? If anyone could offer tips on calibrating a uMB that would be great.

Thanks in advance

Thanks, guess I should have done that first. I found some calibration profiles from other people that work quite well. Makes the colors look much better and the blacks are actually black now
