I agree with the above posts, with only a couple things to add;
1)
Nutrition - This site gives a very detailed look into what is good to give your beardie, nutrition-wise..

2)
UV - Through my own personal experiences, I do NOT recommend using the coil UV bulbs. They cause too many problems and are not a sufficient source of UV light for your beardie. Provided that your beardie's enclosure is in check, according to it's size, the Reptisun 10.0 is a wonderful investment. The UV works at greater distances, from the bulb itself, but also requires a hood fixture to hold it.
Here's another wonderful site I've had the pleasure of finding while I had been "lurking" on the forums in the past...
http://www.petmountain.com/ You can find just about everything you'll need there at affordable prices.
I know that no one wants to spend more money after they just shelled out a good bit trying to get their enclosure set up, but there should never be a lenient or "i'll get what works for right now, and do it right later" mentality when it comes to the love for our animals. Sounds like you're on the right track, though, and I commend you on doing the right thing by researching as much as you can. Good luck!
