I had typed out a whole big thing for ya lastnight, and pressed something stupid and lost it all ,
So I will try again, in a more condensed version, 
It seems so much more complicated than it really is. You just need a basking light, any incandesant bulb that will bring your temps over your basking area to 100 - 105. I have even used a home light bulb 100 watts.
Get one of those silver Dome fixures for it, under it, in your tank, have a nice big rock for basking. I use one of those new fangled temp guns, point/ aim and get instant reading, great TOY!
Along the rest of the top of your screen, you want to put a strip light, kind ya see over fish, and buy a reptisun 5.0 UVB flouresant to fit into strip fixure.
This as I'm sure you know prevents Metabolic bone disease. It simualtes the sun , but nothings better than some real sunshine occasionally!
So your talking 2 lights on top of maybe a 30 or 40 gallon tank, Basking Dome light and long strip with UVB flourensant, NOT TOO BAD ! 
Alot of us go with a 50 lb bag of WASHED playsand from homedepot or lowes, whatever, costs about 4 dollars and something, for one guy it will last. As long as hes not a very young guy, then we use paper towels for awhile.
Shallow water dish, like a shallow saucer, they do drink, if he does not use his bowl, use a dropper drip some on his nose he will learn to lick it.
Also can drip from above, use a papercup with a pinhole and sit it on the screen and let it drip onto a rock below.
They love crickets, we ususally use these as a stable. But roaches, superworms, mealworms, wax worms, butter worms, MOTHS that flitter around
, flies, spiders, well all small crawlies,
as long as they are safe and not poisoned from sprays.
So nice your going to go get him and give him a home,
we love lizards around here, and love their photos too, so get yoru camera ready also *SMILE.
Again Glad your here. Anymore questions give us a holler, you can see howmany people have already jumped in with great info!
