No, you need to send no such papers. All you need to do is attach a copy of your green card (front and back) as well as the filing fee.
You will be asked during the interview to prove that you are still married to the same husband through you obtained your green card and that you are still living in "marital union" in the same household together.

Attorney Robert Brown's (former INS Director, 1972-99) reply to your question is general in nature, and does not constitute legal advice as all facts are known to him. For specific advice or representation you should retain an attorney experienced in immigration law. Mr. Brown's reply on AVVO does not create an attorney/client relationship not constitute legal advice.
I am not really sure what your question is or what you mean by "as before." If you are applying for citizenship, and you are a green card holder, you need to file form N-400. This form is not easy to fill out and has many hidden "trap doors" for lack of a better phrase. I highly recommend you think about hiring an attorney to help you through this process. The N-400 was recently revised and is now over 20 pages! Even experienced attorneys complain that it gives then nightmares.
