agree, Andy's book is pretty good. i dont think the books is great, however. it could do better explaining the different settings and what they do. its does some of this, and reading and learning those really helps.
i have thought of writing my own explanations on the different settings like iron audio, silencer, audio response, etc etc etc. the best way, for me, to learn the deus settings, is to read about each option and what it does, AND how it may be affected by the other options as they are often interrelated.
Calabash has some very informative videos also. his videos are real world, so to speak and show you the options and their affect in the field. so does a guy from UK named Gary. he has a system of 10 videos on the deus. i suggest watching them all, then watch them again as you learn the machine.
