Nokia 6682 / 6681

Ok guys, I'm sorta new to these advanced cell phones and all. I just got the 6682 the other day and was wondering what you have to do to play other forms of music besides MP3 files. Is there a way to play wav or windows media music files which take up less memory than MP3's? And as far as watching videos/movies on the phone, what all do you have to do in order to do this? thanks in advance-
