No, Form G-325A is not required for naturalization. For any type of application, the published USCIS instructions tell you which forms need to be included.
This is general information only. It is not intended as a substitute for legal advice, and does not create an attorney-client relationship.

I agree with my colleagues, it is not required. But the information you provided in the G-325A and that in the N-400 should match (depending on how many years ago you submitted the G-325A form).
As F.J. said you should consider hiring an attorney.
