So much Bach, where do I start?

The Walcha "complete" organ works on CD can be ordered from europe, try http://www.crotchet.co.uk. I just read in the Grammophone that it is due to be released in the US. MC Alain also did the complete Bach organ works, I have them on vinyl and find them an excellent alternative to Walcha, who is really my favorite in this music. I think only selections were re recorded or released on Erato.

I'll put in a plug for Christopher Herrick's Bach organ works cycle on Hyperion, well-recorded for the most part and well registered and played. I had the pleasure of meeting Christopher (he stayed at my home for a few days during an AGO workshop and concert at my church a few years ago), and found him to be a lot of fun but also a very serious musician, particularly with respect to his interpretations of Bach. The next summer I got to hear him play a number of concerts when he played all of the Bach organ works over a two-plus week period at Lincoln Center, quite a feat. Aside from his ability to master the technical demands of Bach's music, I find his taste in registrations to be excellent. As a good example of his playing, I'd recommend his Hyperion recording of the Bach Trio Sonatas, a reverberant and perhaps slightly bright recording which conveys the beauty and intricacy of those pieces, one of my favorite Bach organ discs.

Greg, you are quite welcome and thank you for taking a chance on my opinions.
