you don't need to put it all. What is your goal? your focus? Start there.
You can group shows by area (starting w better known directors/theaters) or types or recent work, depending on what you are seeking. You don't need to list everything you've ever done, just a sampling, with (for example) shows using animation or lots of rail cues being included when you go for a theater or a show that uses that skill. And, school shows will fall by the wayside as you replace them with professional work.
Fwiw PSMKay had a great suggestion a week or so ago about creating specific structures so you can easily rearrange your resume for something in a specific discipline.
And, at the bottom, you can list other skills /training/unions where appropriate. It shd still fit on a page if possible (tho mine is 2 pages, with the "other" things on p. 2)
(and, sorry, this post didn't pop up until today, prob my system, so apologies for not generating a discussion sooner)
