Here's what I've heard: CV - yes Publications - no, unless they ask you to bring them (I've had a few ask) Notebook paper - yes ERAS Application - no Of course, everyone will have different opinions, but this is what I've heard from a few different people.

I kept a copy of my CV and eras application just in case. Didn't have to use it at all. But you never know.

IF you have published a paper, (not an abstract), then I would bring a few copies. I was asked at multiple interviews about my research. One program specifically wanted my papers. The others I simply offered it if my specific publications were brought up.
