No, you have to wait until NVC generates DS 3032 (choice of agent) and AOS Feel Bill. So don't email them after NVC assigns your case number, rather wait for the above.

Hello, today I received an email from NVC saying that the have received my files and whenthey put the infomation into the computer they will give me the case#. Do I have to wait until I get the case# to send the email for the DS3032? How long does it takes to get a case# after NVC email you? also I haven't receive the letter for NOA2 is this is good?

Thanks for all your help...
The DS3032 is for your I-130. If you don't want to pursue the I-130 for CR1, you need not respond to anything from NVC regarding it. NVC will not ask you for anything by mail related to K3.
To clarify, you have not applied for any visa yet. You have petitioned for your spouse to have the privilege of applying for one or both of two visas.
