heya, if you are really serious about wanting to learn facial expressions I recommend you find any/all books you can by Dr. Paul Ekman He has made a study of the human face and how it conveys expression. Two of his books that are excellent source of info are Unmaskng the Face, and Telling Lies. It is my hope - should I ever find time enough to get around to it - to sit down and make up the different base expressions for Poser. It is from these base expressions that all our facial expressions are formed. You will see what I mean if you check out the book and see the face cards he has designed for test recognition purposes.
