I know I'm coming to this discussion late, but I've just recently discovered BYC.
I used to run a bearded dragon mailing list. In fact, I'm still listed as the list owner although I haven't been very active in the herp community for several years. The list I'm talking about is
http://pets.groups.yahoo.com/group/pogona/ . (Pogona is Pogona vitticeps, the scientific name for bearded dragons.) The list will have a number of people who are experts in BDs, including breeding in case you get any more eggs. BDs don't become eggbound very often, so it's not the same level of worry as if you had chameleons.
Of the books you now have, Steve Grenard's is best. Steve is a very knowledgeable herper who puts a lot of time and energy into learning about herps and then writing about them. The Pogona list is cited in his book, but he has the old address for the list before it was moved to yahoo.
There is also a BD forum on Kingsnake at

Your BDs, and in fact the other BDs whose pictures I've seen in this thread, all look healthy to me. You may want to have stool samples checked for parasites though.
I'd also be happy to answer specific questions as well.
