Let us know what parts you NEED and what parts can be had later.
Body parts are always going to be expensive unless you find someone who is parting out a bike that was damaged from the section that yours wasn't.
We always recommend
www.ronayers.com for most factory parts. And even if you don't use that site, it's microfiche and all of the available part numbers are immensely helpful in locating the same part of different sites or for cross reference. So I'll go ahead and mention it.
Give us the part break down and we can help you further.
And for the record, everyone goes down. Don't let it mess with your psyche or anything. You had on gear, as you should, and you got up and walked away nearly unscathed because of it. Take not, everyone reading this thread or who has ever been on two wheels.
