In terms of providing everything since date of marriage VS only new stuff since I-485, there's two schools of thought.
This forum has people who got approved by submitting everything, and people who submitted only updated information.
It's up to you which path you choose. The only thing I can think of, if you're already paying lawyer to file, it's likely a fixed fee. You won't incur any extra charges for extra 100 pages printed, so might as well 😃
That's what I did - send lawyer all docs from start of marriage electronically and they took care of printing and assembling the packet. Was it an overkill? The time will tell, as my petition is still pending. But I feel better knowing I followed USCIS instructions to the T.
