I just want to make sure about this. If I have used Space Designer, but I have chosen impulse responses that are included in Logic (just their already made impulse responses), and not tweaked them in any way, then when I save a Copy of the Project, I would think that I do NOT have to check the box "Copy space designer impulse responses to Project Folder" -- am right? In other words, is this box only for impulse responses that you have tweaked to make your own?

Hi Alex Saving the impulse responses to the project folder would be useful if you plan to share the project with someone else or on another Mac/version of Logic where you're not certain that system will have the full install or the same content. I don't save impulse responses or EXS24 instrument files to my project folder unless I am passing the project to a collaborator. Definitely, if you have created your own IRs then you normally shouldn't need to save them to the project folder unless you're archiving your projects or sharing it with someone else/another system.
