You have a pretty good list there (aside from Anoles--I wouldn't recommend them for beginners as they're skittish and usually wild caught [read: parasites and guaranteed vet bills for your $5 lizard])! I can't think of anything else to add, so instead I'll throw up a few good resources for the ones on your list so you're better able to research and decide which is best for you.
First of all, Bearded Dragons themselves: You've already found this forum, and in the Articles section, there's a good
caresheet with links to other caresheets (including the one at BeautifulDragons.com, one of my favorites in part for their Nutrition page)... So you're pretty set on that front!
So we come to Leopard Geckos... With Leos, it's tough to find a dedicated website, but the
care sheet over at
http://geckoforums.net/ is a good one, and they have a Leopard gecko forum where you can get some advice, too. That same site has a forum for Fat Tail Geckos, so you should be able to read up on AFT care there, too.
For Blue Tongue Skinks,
http://bluetongueskinks.net/ is a GREAT resource. They also have a forum--you can find the link in the menu on the left. It appears to be down right now due to a bandwidth issue, but it's definitely the place to go for BTS info once they're back up and running!
For Crested Geckos, as well as the other Rhacodactylus geckos, there are two forums that are considered
the places to go among Rhacodactylus/Crestie keepers. Those are the Repashy forums,
http://www.forums.repashy.com/, and the Pangea forums,
http://www.pangeareptile.com/forums/index.php. You might look into Gargoyle geckos, another Rhacodactylus. They're a little more sensitive than Cresties, but they can also be a good beginner gecko.
I don't know of any good resources for Anoles. What I know of them is that they're insectivores, require UVB (much like beardies and skinks), and are active and arboreal in nature--meaning, they should have a sizable and tall enclosure. Just because they can survive in a 10 gallon, doesn't mean they should be kept in one! You might give this a read; it seems to have some good information, and it's probably a better resource than the "eHow" caresheets that come up in a google search:

Hope this is helpful to you
