UML, like most other tools, is pretty useful in moderation. It's not a solution to every problem, but for a lot of situations where you have a big project it can help to have a little overview of the process. From my experience, I'm inclined to agree with your conclusion about the most useful bits. At the same time, I don't agree at all that good diagrams should only be used for small parts of your project. Unless we're talking hobby projects, in which case anything goes.
