Book recommendation: analysis phase best practices - needs analysis, database layout, questions to ask

This will be the year of Drupal for me. I've already bought the following books:

• Using Drupal
• Drupal 6 Themes
• Drupal 6 Javascript & jQuery
• Front-end Drupal

I'm ready to begin my first project, converting a small site I made years ago back in San Francisco - I have intimate knowledge of the functionality & needs met by the existing site.

I'm quite leery of just jumping in and building the site in an ad-hoc manner. Structural decisions made early on may be tough to change afterwards. We're talking databases and other scary entities! <grin> I feel I should read one more book to guide me in that initial analysis phase: how do I map project requirements to Drupal concepts? What are best practices before I even touch the Admin panel for the first time? What questions should I ask the client?

Please recommend a Drupal book addressing best practices in the analysis phase. Thanks!
