Good advice so far.
Also - many shops will try to sell you multiple beardies for one viv. If they do, don't listen to them - Beardies are best kept on their own. The shops usually have a glut of animals to sell, so often try to sell groups. Males will fight (females may do so as well) and you'll have bullying / dominance problems whatever you have. We all know what will happen if you have a mixed community! It may be that you would be delighted to breed them, but the female needs to be old enough to cope with it.
If you can stand the wait, it would be well worth going to one of the Reptile Shows. There's loads of info on here about them:
