Congrats on your husband landing!
I went to get my visa in person, and I got
some evidence back. We got back some print outs of our interactions on LiveJournal, and part of our Skype logs... I think that's it? Didn't get email evidence, photos, certificates or anything else back. I would say, all in all, we got 1/5 back only. I personally don't mind, since I have originals for everything we sent (and a nice digital copy of the whole final package).
By the way, I'm one of those for whom emailing the office worked. I emailed them on Thursday to inform them of my pregnancy, and they called on Friday to tell me if I wanted I could get my visa right away
From the call, I got the impression that they either hadn't opened my file at all until I emailed them, OR they had looked at it before, decided I could be granted the PR... but never actually contacted me to let me know; like they were waiting for me to be closer to the official timelines or something. So, I'm really glad I emailed them, for now I'm a landed resident and my baby will be born in Canada
