Is this going to be a visiting artist type thing? Talk with current students, maybe give a master class, and have an exhibit of your work?
I'd want to be able to give a presentation on my work and talk about it with students and other interested parties. That usually means a digital projector and Powerpoint slides (though I usually just use Photo Mechanic to show my work.) But I think prints are also important -- they give the students a finished product to see and touch and feel. Maybe it will inspire one of them to follow in your footsteps...
I'd bring a portfolio case of prints in various stages, some work prints and some finished prints.
If there is to be a gallery show, then of course you'll need mounted prints. That's something to discuss with the gallery director.
I would not count on selling anything, even if there is a gallery show.
