Well, my first recommendation is to buy from a reputable breeder to make sure you're getting a healthy animal. This species is sensitive to stress and can be difficult to acclimate.
If you insist on getting an animal you know is thin and presumably carrying parasites, make sure your vet knows uros. Get the fecal check as soon as possible, and have your vet help you right away if the uro doesn't seem to be doing well.
Get a very large cage (at least 4ft x 2ft footprint) as wild caught geyri do not do well AT ALL trying to acclimate in smaller cages.
Do not use a night light. If you need night heat (to keep it around 75 or so), use a ceramic heat emitter. For the daytime, basking surface temps should be 120-130F, a good part of the cage between 95-100F, and a cool area around 85F. Don't guess at your temperatures - be sure to get quality digital and/or infrared thermometers to moniter the cage. Be sure you have a quality UVB light mounted an appropriate distance away.
Don't soak your uro. But when you first get it and during any medication, offer a small, shallow dish of water for a few hours each day to make sure he can drink if he needs to (not uncommon with wild caught geyri).
Use low, snug hides - in other words, not commercially purchased hides. The best ones are made with paver bricks and slate tiles. They like hides that they can feel against their backs. 1-1/2" is a great height - more or less depending on the size of the uro.
Uros should eat primarily plant matter. Don't feed bugs when you first get him. If you choose to feed bugs once he's healthy, only feed very sparingly (as in one or two bugs in several weeks). Do lots of research on good nutrition, as it's very complicated.
Do plenty of reading. Here are some good places to start:
