WOW sorry to hear about the accident. But Jobob is right don't sign anything you dont understand or are not sure of. Get some one you trust to read it. And by god they should have to replace NEW everything they damaged.
Bike helmet ect. And make sure you wait to sign off on the medical stuff until you are sure thing are ok. Some times it takes a while for some thing to show up.
Take care and hope you are feeling better soon.
