So I was placing something on a high shelf and it fell of directly on my 2 day old macbook

There is a huge scratch on the back of the computer by the apple logo which is also slightly dented...
I turn my computer on, everything seems to be working okay. But now every 5-10 seconds or less, a part inside the computer seems to be shaking making almost a clicking noise. Now I know that accidental damage isnt covered in Apples warranty, and probably not in Apple Care either.
Am I screwed? Do I have any options to try and get it fixed? The back i dont really care about, I can buy a case. But the noise cant be good. it happens most when Im typing or moving the computer so I assume the part is just floating around inside the computer.
Please tell me that there is something I can do.
anyone?
