Very good and comprehensive article. In relation to rule #8, it might be worth adding that it's a huge advantage if you can find band members who can learn music by ear. Aside from the obvious perk that you don't have to spend time finding or writing out chord sheets, it means you can bring a new tune to rehearsal and stand a chance of the band being able to jam it, and especially if you find you have to transpose a song for the singer's voice then there's a much better chance of being able to do it on the spot. I've also found that people who can link the sound to the notes automatically tend to memorize music more firmly than people who work off paper. Hope that's useful.:-)
