I need to know if i have enough supplies for my bearded dragon?

I bought a 20-25 gallon tank; I think its a breeder tank. Not sure. I bought repti-sand and filled it up and a inch maybe a little more around the entire tank. I bought a basking rock. I have a basking light, night light,and a uvb light. I didnt have enough for a water dish, a hydrometer,or a pooper scooper. But I might get a thermometer. I'm going to purchase my bearded dragon on June 14th 2011. Im also getting the thermometer, if i can. And a box of 200 crickets (dead) and a box of 200 mealworms (also dead). Thats all i can afford now and on June 23rd 2011 im going to purchase a pooper scooper, hopefully a hydrometer and maybe a branch that can cast shade. Can i get maybe half a shoe box (for now) and cut a hole for it to crawl in and out for a hiding place? itll only be until i can get the branches of course but is it ok? and im also getting the water bowl on the 16th. im not getting a food bowl because im going to hand feed it. did i get enough stuff for now?
