I was planning on using InDesign for typesetting and layout and hiring a graphic designer for the book cover/back. My book has lots of bulleted lists since its a study guide and would probably cost a fortune to have someone format it for me. So hence why I'm curious about InDesign and possibly doing it myself....
InDesign requires you to learn a fair amount about typesetting, and to have an eye for the shape of text. It's a learnable skill, but it's not something to pick up while you're working on your first publication.
Bulleted lists are dead easy, by the way; most word processors have a built in style for them, and you can easily customize it.
Given that you're creating a study guide, and they usually have lots of white space, honestly, you might be better off either paying a typesetter 250.00 or so (depending on the size of the work and the labor) to do it for you, or simply make do with MSWord or whatever word processor your use.
It isn't going to look fabulous, but you can certainly produce something that won't embarrass you, and you may very well learn enough about the basics of design and typesetting to make InDesign worth the extra expense and the learning curve for your next project.
Keep the design/layout and typography simple.
