There are a ton of good books...and probably equally as many bad books written on the disciplines of the Christian life.  I have found 3 particularly valuable: Dallas Willard "Spirit of the Disciplines"--I think the benefit of this book is that is gives a good philosophical foundation a good theoretical foundation and a good historical foundation for the Spiritual Disciplines; Richard Foster "Celebration of Discipline"--This book gives some of the best practical guidance on "how to" implement the disciplines in our lives; Don Whitney "Spiritual Disciplines of the Christian Life"--This book gives a Biblical foundation for many of the disciplines discussed in the prior to books.  I think that in answer to your question Whitney's book would be a good place to start.  You could also check out his website which might be helpful.  http://www.spiritualdisciplines.org/

I, too, have gained much from reading and re-reading Willard's Spirit of the Disciplines, as well as Foster's book and Whitney's. I also found "Disciplines of Grace" by T.M. Moore very interesting. His section on prayer is exceptional and he also has a chapter on spiritual friendships that is noteworthy.
