For Section 7 you'd need Kushner, because he has a couple of chapters in the second half of his book that focus on this specific objective.
But where I found a great source of information is IBM's developerWorks site. It has enough articles in a tutorial fashion that show you the ins an outs of validation, tuning, and troubleshooting. The articles are not always aimed solely on the aforementioned issues, but they can also be case studies that include them as an integral part.
Check for Barcia's articles, a senior developer at IBM.
