Form 3531

I was required to mail my taxes in this year instead of e-filing.  I failed to sign and date the 1040 and the CA state form.  I received my 1040 back yesterday, approximately 3 months later with a green 3531 coversheet with box 1 checked.  Here are my questions.

1.  What date should I use with my signature?  The original date that I printed it out from TT and sent it in or today's date?

2.  I had submitted it early before the tax deadline but will it now be late?  If so, will there be a fine?

3.  What should I do about the State filing which I did not sign either but have not heard yet from the State?

4.  Any other advice for me to make sure this gets processed correctly?  (I know it was fully my fault for this whole mess :( )

Thank you for any information you can provide.
