The Stone Lantern book is ok. As Chris mentions, the book is a compilation of various articles from Bonsai Today (which I believe were translated from Japanese articles), so it can be a bit confusing since different terminology is used, etc. The disappointing thing for me was that Stone Lantern took the easy way out by just reprinting articles, rather than writing something from scratch that would outline everything someone using pine for bonsai would find important.
In any event, the book is a good start. I would also look at an article from Hans van Meer which you can find on the web, which to me is the clearest articulation of what you should do season to season (and this is written by a guy whose first language I believe is not in english, yet it's the most clear writing on pines I've come across). Also, Brian van Fleet has a very good pictorial of a 3-year progression of what he has done with one of his JBPs, which I highly recommend. I think it's available at:
www.nebaribonsai.com. I also have Steve Pilacik's (sp?) book, which you can find on eBay. It's pretty good, but I think like most other works on pines, it could be written a little clearer. It made more sense to me after reading the Stone Lantern book and Hans' article.
Another resource is Boon's videos on JBPs - one on repotting, one on candling. I haven't viewed them yet, but I've heard that they are very highly rated. I think Santa is going to be making a second trip to my house this year...
As you can tell, I've spent a lot of time trying to find articles, etc. to help me figure out the whole JBP thing. Once you understand the growth principles, the techniques make a lot more sense.
Hope that helps!
