...The other day I did notice that there was some orange in the urate.
...Screen cage about 2'x2'2.5'.
...There is a 75 watt infrared heat lamp on 24 hours that sits above the top of his enclosure. Recently I have also added a second infared bulb along the side of his enclosure
...He also has a 13 watt UVB bulb that is on the side of his cage that is on about 13 hours a day
...The average temperature is about 75 degrees with it about 65 on the floor and about 95 in the basking area. There is a thermometer on the side of the enclosure.
Humidity - Not sure about humidity. I do mist the enclosure twice a day.
Current Problem - ...has been hanging upside down or on his side a lot.
...he will sometimes sleep during the day now too...
Howdy Shannon,
A number of things have already been covered in other posts but I'll add a few and duplicate some too

.
Orange urates, as you know, suggest dehydration but the can also be a sign of kidney problems/failure.
If he makes it through this, you'll want to upgrade to a larger enclosure.
Change the Infrared light to a single ~75W incandescent (Home Depot 60W halogen FLOOD is fine) and place it on top, pointing downward. Don't trust the thermometer. Do two things to verify the temps of the new light:
1.) Stick the back of your hand at the basking spot and if it just feels warm but not hot then you are not overheating.
2.) Get a low-cost infrared temp gun to check his skin temp.
The Exo-Terra Repti-Glo CFL and linear UVB tubes have had some manufacturing inconsistencies that may leave the buyer with a product that could be producing inadequate UVB levels and/or non-terrestrial spectral content. Until these are ironed out by the manufacturer, use a ZooMed Reptisun 5.0 linear tube and place it on top, aimed downward (not on the side of the enclosure) 6"-12" away from his basking spot.
Get a simple Lowe's AccuRate digital temp/humidity meter and verify that the humidity is above 40%.
Hanging upside-down and sleeping during the day are sure signs of serious troubles. I've often wondered if hanging upside-down was a way of relieving internal pressures on troubled organs like the liver, but that is just speculation on my part.
EDIT: I meant to add that it may also be useful to create an environment that minimizes the chances of falling and give him more options to move without ending upside-down. Maybe lots of vine-like material that lets him hold on while staying rightside-up.
