Hey.
I wrote the book, so I'll try and answer some questions.
As to the integration of Eastern into Western, there is a solid element of that included in there.
The Alternative Fighting Schools section includes monk mods to allow you to create both western boxer and wrestler archetypes, with replacement special abilities appropriate to each.
Several of the prestige classes are suitable for western characters as well. The Iron Legs Kickboxer, in particular, is great for a boxer archetype. Just change the name to "Iron Fists Pugilist" and you are good to go.
There are quite a number of feats that are very appropriate for western martial artists.
The character concepts chapter also includes a concept for a western boxer, and many of the others fit as easily into a western setting as they do an eastern one.
There is also a section on tournament rules that includes sections on boxing, greco-wrestling (pankration), and Corno-Breton wrestling.
I'm very concious of the fact that many people have difficulty reconciling the monk into the a "standard" fantasy setting, which is why I included the stuff listed above.
