MS & Cisco dominate the cert scene with millions of certified individuals. I mention that, because the publishing houses run these numbers to determine for which certs to do study guides. So if you look at those with the biggest numbers (quality is not the determining factor here), you'll most likely find study guides and books. If it is specialized and the numbers are small, then we're SOL. This is why you can find guides for CISSP, Security+, CEH, CISA and a few others, but not many exist for the very specialized credentials such as those in your list below. Hope this explains why you're not seeing them.
On the other hand, you can find some great info online if you know where to look. Start by going to the site for each cert that interests you. There is always at least an outline of what is covered. You can take that and then research on your own. When you find some great resources, be sure to share them here in the respective Forum Board for that given cert. ;)
If you're lucky, some courses actually use a published book as the textbook for the course such as CEPT and the book Shellcoder's Handbook.
One could also argue that this is why these credentails are better. They require you to do more than just read a guide and take a test. On the flip side of that argument is that if a cert program is not popular enough for a guide, then will anyone recognize it's value on your resume. Hmmmmm...
Hope this helps,
CISSP, MCSE, CSTA, Security+ SME
