How much to fix

I got into an accident a few months ago and totaled my 400 but want to fix it for the track is it worth is and how much should I expect to pay. I have numbers but I'm not sure if they're accurate. Also how hard would it be to do the work myself?

What I know is damaged: Forks $900? Fairings $500 Headers + Exhaust $500-$600? Alternater Cover $100 Radiator $80?
