first thing i'd do is replace the helmet if you want to get back on a bike. I'm a firm believer in having the best helmets out there. your body is no good without a good head on its shoulders. without a good head, you aint shit. as for the bike, ebay for new parts. if not, go to www.mrcycles.com. they sell parts at wholesale. i've been from them for about 5 years now. you lucked out man, could've been alot worse. glad to hear your ok.
