1) Call police department and ask for copy of report
2) file claim with his insurance company (give them report number, they will get their own police report)
3) tell them you will get checked out by your doctor and plan to leave medical open for a while
4) see what they offer you to close early, they will probably offer you something immediately (do NOT suggest any numbers at this time or ever too them) - likely it will include medical and some amount of damages (personal and equipment) - do not, at this time, give them your evaluation of your bike's worth
5) Go to your doctor! Get his expert opinion on your body (things can hide for days). Get a second opinion from a Chiropractor.
6) Decide what you want to accept from them on damages - don't let them close medical for a month or so (though if they offer you a lot to close the medical, you may want to consider taking it)

7) - If the insurance adjuster seems to be acting like a dick (not if you *think* he's lowballing an offer), tell him you'll call a lawyer and get back in touch with you. If he's acting like a dick, it's a sure sign he thinks he can roll all over you. Insurance adjusters should be willing to come darn close to licking your backside in an attempt to keep you happy throughout the process if the report says the driver is at fault.
