Cracked tennis raquet, possible fix?

Okay, so I have a prince hybrid sharapova (something like that) anyways, I had a bipolar meltdown and chucked it.. So, the top part, where the plastic cover to protect is it, broke partially but is still held on by the other half. Underneath that, the raquet metal frame cracked and is dented inward, but only the "outerframe" its a thick frame, and i believe it is hollow inside, and it is only cracked on the outermost part. I'm positive i can't fix the metal, but can i fix the plastic covering? Will the cracked metal effect my game?
