Pretty comprehensive but I think you should have also mentioned Copperhill Images http://www.copperhillimages.com/ as a good source of supplies at more affordable prices than Visible Dust.
Also, a good quality nylon artist brush can be purchased at any good art supply store for less than $10 that is more than sufficient for dry cleaning sensors much cheaper than products like the Arctic Butterfly.
I'm not critisizing the Visible Dust products, just pointing out that there are cheaper, alternative products available.
