Martin,
Yes. Every last process in the PMBOK Guide has a section for Inputs, Tools & Techniques, and Outputs. But not just one of each... off the top of my head I would estimate that (on average) every process has 3-5 Inputs, 3-5 Tools & Techniques, and then also 3-5 Outputs.
And yes, that is indeed a lot to learn. But once you understand not just which ITTOs we have for each process, but more importantly WHY we have them, then things become much clearer fast.
