i understand your concern, for the amount you paid greater quality control should be employed, unfortunately, the macbook pros seem to have slipped through the nets (maybe in the rush to get them on the shelves?) and so we have such issues.
My girlfiends mbp also has a keyboard that isn't level and a wonky screen!
its not right, its like buying designer clothes whose stitching is wrong.
My advice would be that if you are that unhappy, try to get a new one, although then you risk getting one with more serious problems (heat/whine etc).
