Check out
http://www.Edmunds.com for the invoice prices and MSRP. You can price it with whatever options you want and it's right on.
If you're looking to buy you should check out Auto Club's Member New Car Purchase program
http://www.aaa-calif.com/auto/. I believe you'll pay $500 over invoice for the CE, LE, and SE, while you'll pay $750 over invoice for the XLE. I think the hybrid is exempt. If you have a credit union like the Orange County Teachers Federal Credit Union they also have a similar program. No price haggling or any hassels at the dealership. They will show you the invoice and an approved letter from either the Auto Club or OCTFCU that shows how much you pay over invoice.
Hope this info helps.
Also, the invoice for the model you were asking about is:
2007 Camry LE with Auto Transmission - Invoice:$18,348 - MSRP:$20,500
2007 Camry LE with Manual Transmission - Invoice:$17,407 - MSRP:$19,450
