I-485 Questions

We are getting ready to file the I-485 for Adjustment of Status for my wife that came over on a K-1 Visa. Looking at the documentation that is listed to include with the I-485 form, it appears that most if not all of that was included in her K-1 packet that they took when she entered the country. Do we need to go through and fill out all those forms and find all the evidence again; even though it was included in the K-1 packet that the CBP officer took at the airport?

Any help would be greatly appreciated.
