We did not have an I-485 RFE like your's, but we did have a couple of opportunities to respond to USCIS during our green card process (see our Profile). In both responses, we submitted quickly at the earliest.
My thoughts were if our paperwork is on some desk, best to respond sooner while it is near the top of the stack than to delay any more before it goes to the bottom of the pile. So if those evidences are all you have, I would submit them as soon as possible, and maybe include a short explanation to support the evidences in the cover letter along with a copy of the RFE letter. Good luck.
