Sorry to say, you were given very bad advice, a 10 gallon tank is way to small, these lizards are extremely active and love to run and jump, and just be lizards.
You should have atleast minimum 20 long but even that is pushing it, 30 gallon long, is the best choice if your trying to keep it reasonable. Always rememeber with these guys BIGGER IS BETTER.
You really should have the tank in a place with no air conditioner, these are desert lizards!
But many people have central air so ya just have to get the heat up in the tank.
The way you have to set the tank up is to have a basking rock or area, with a basking light above, the temperature at the basking area should be 100- 105
The rest of tank should be about high 80's to 90 degrees, so you can see why it will be hard to acheive in an air conditioned room.
Also you can not acheive that temperature gradient in a small 10 gallon tank.
And you will also need a long flouresant UVB light this is to help with vit. D3 so as NOT to develope Metabolic Bone Diease from lack of calcuim. It acts as Sunlight.
These lights stay on from early morning till dark about 12 hours or so.
Good news is you DO NOT have to leave them on all night while your trying to sleep, 
They drink water every day, in shallow saucer or driped from a melting icecube placed on the top screen and dripping down on a rock below.
They eat crickets, superworms, wax worms, silkworms, moths, grasshoppers, japenese beeteles
as long as they are pesticide free of course.
Oh and the bugs should be gutloaded before feeding, meaning the only nutrition your lizard gets is from what your bugs eat, so feed the bugs, greens, sheredded carrots, dried catfood or dog food, fish food, cereals, they are not picky!
Also you need to dust your bugs atleast 3 times aweek with calcuim power I personally use "Sticky Tongue miner- all for indoor reptiles."
You can sprinkle some in a baggie, put bugs in, and SHAKE AND BAKE type thing except no baking, just SNACKING !
Well thats about all, for now, I have to run, but many people on here can help you if you have any more questions just give us a yell ! 
Good luck, and again NICE to have you !
