Hi Curious1, I just saw your post.
The sleep tracks are nothing new. Let me explain. The script between the old and the new paraliminals is identical. What is called a sleep track is the portion of the paraliminal where the multiple voices begin (i.e. after the induction/count down 5,3,4,2,1). The main difference is the Holosync track that is added (which by the way is not only added in the sleep track section but throughout the paraliminal).
In other words, everything is the same, with the only addition being that of the Holosync alpha or theta binaural beat track (depending on the paraliminal). However, since on CD we have the added convenience of having "tracks", LSC decided to partition each paraliminal to a few tracks, usually:
Track 1: Introduction (setting the goal for the session)
Track 2: Induction / count-down / relaxation (call it what you like)
Track 3: Sleep track (in other words, where the main change work occurs)
Track 4: count up from 1 to 5
Now, regarding your second question. If you have the Ideal Mindset, Decisive Action & Consistent Achievement manuals, you do not need to get the new CD just for their booklets - they are (as you guessed) very similar, if not identical. I've only managed to get the Consistent Achievement before it ran out of stock and I don't think I've gained anything new from the manual (apart from the intro stuff on how to set goals & objectives). However, the plus of these courses are the coaching audio sessions by Paul which are excellent.
