I found this book really helpful. I'm pretty public about the fact that methods freak me out (technically just the analysis framework, but let's generalise), and this book was useful to both reassure me that what I'm doing is valid and legitimate, and guide and improve my question development.
One thing I found odd were the questions in the appendix - weird issues were being investigated, like the role of churches in reducing teen drug use, and teenage pregnancy. One question made me laugh, though - it asked what could be done at the church to "turn you on". So that was exciting.
Either way, I found this helpful, and will probably rent the planning book on Kindle next.
