The short answer is no.
All of the modifications are made in the database, and that cannot be divided easily into groups of changes.
If you want to make the changes yourself, you can download DWedit from Bill Nichol's site
www.subguru.com and use that to edit the stock database directly, using the LWAMI Mod changes as a guide.
Cheers,
David
PS No there is no easy guidebook to DWedit, the community can help you if you have specific questions, but the best way to learn is more to less to experiment on your own, the program is actually quite nice to use once you get the basics down of what various aspects of the database mean and how they impact gameplay.
