After hearing the SFQ tapes I looked into Feng Shui, courtesy of the internet and my local library. There's alot of superstition and propogated myth out there.
A few books stood out from the dozen or more I photoread/browsed ...
Feng Shui Handbook - Master Lam Kam Chuen
Feng Shui for Skeptics - Katar Diamond
Complete Idiot's Guide to Feng Shui - Joseph Yu
Don't be put off by the title of the last one, it is a gem.
There are hundreds if not thousands of websites also. Almost all of them are trying to sell you their course, but mixed in among the ads are some real good information. I've got to dig out my old bookmarks.
I'm surprised more folks have not posted a reply.
