Anyone have a recommendation for what to read after the first ACT text?

I am wondering if anyone has a recommendation for a good book to use for further learning after finishing the main act text Acceptance and Commitment Therapy: An Experiential Approach to Behavior Change by Hayes et al.  I was thinking of either Learning Act: An Acceptance & Commitment Therapy Skills-Training Manual for Therapists OR A Practical Guide to Acceptance and Commitment Therapy.  I want to learn how to solidify my knowledge more after reading the original text on the subject.  Do either of those books sound good as a next step or is there a different approach or a different book that I might like more for the stage I am at?  I did get Forsyth's self-help book on ACT for anxiety and I also got the Hayes self-help book Get Out of Your Mind and Into Your Life.  Would it help if I used those on myself so that I had a first hand experience of the therapy?  Because it is an experiential approach to therapy, it seems that I might do best to do both of those self-help books.  Then, maybe I could go on to read those other books?  I'd greatly appreciate it because I want to be highly competent in this therapy as soon as possible.  Maybe I answered my own question, but no one in my clinic knows anything about this therapy, so your support would be greatly appreciated!  Thanks!
