I did a poster session in DC and was almost mauled by people. I have two suggestions based on that experience.
ONE PAGE Handout- for simplicity of distribution and for cost of printing and hauling to the conference. The one page handout says you you are, how to locate your information and poster details online, perhaps a screen shot to remind them what they are looking at. Let them do the rest.
OLD BUSINESS CARDS- I needed to get rid of some old business cards, so I could get some fresh ones. I took the old ones to the poster and had people write my twitter feed or take notes on the back. They all disappeared! (close to 300)
I would not plan on handing out copies of my presentation unless it is a limited number for extremely interested people.
The case study in a nice idea. I wonder how you can get that to one page or print two sided?
