IMHO there is no book written that will give you all the information you need. The reason we went nano was so that we could learn the business with minimal risk - we kept our fulltime jobs - and carry no debt. We don't rely on the brewery for income so the pressure to produce isn't there. There are plenty of other pressures and stresses but those will vary by individual, location and market.
I didn't believe that the "work in another brewery and learn the ropes" was a good route - I sure don't want someone hanging around and getting in my way when I am brewing but would be happy to have someones else do the shit jobs - but I am kind of a prick. The advice that you can only make it if you get a 30bbl brewhouse and a bottling line that does 10 cases an hour wasn't an option either, and I can't imagine doing brewpub.
At some point one has to shit or get off the pot. If you want to work hard and make no money while you learn the business why not go nano instead of being someone's brewery bitch? You'll learn everything about the brewery that way.
Good beer sells and everybody wants to at least try a local product. Getting someone to try your beer isn't that hard. Keeping the business is another story.
Good luck and feel free to contact me if you want.
