The best resource for learning about Apache CouchDB is the project website. There are more resources to find, both within the website and on the CouchDB mailing list archives.
Community Over Code has some great links for learning about The Apache Way. In particular, we have a wide variety of feeds you can read about everything Apache.
An excellent reference to The Apache Way is JAaron Farr's most excellent presentation entitled "The Apache Way" which was given at the past few ApacheCons.
