Welcome to the site! While I cannot yet find the Official Pricing link strait from GM, it has been announced, along with many options. Also I would not give that dealer any money until you find out what their allotment is, and if you would be in the first one. That information is avaliable to the dealer as well, and they should definately know how to access that information.
Edit: Ok I could not find anything straight from the GM website about options pricing, but
this thread has the official pricing, and you can print that out to take to your dealer, and it has the same info that will be on the computer when he puts in your order.
This is the pdf file that contains detailed info on the options and equipment groups, if you have not looked at it already.
As far as allocation goes, tell your dealer to log into chevylaunch.com with their Business Associate Code and go to 2010 camaro section then to the ditribution portion of the camaro main page. It tells them their production number. (that info courtesy of a previous post by Sizzox).
