By looking at the pictures, I would say that he looks very unhappy. I also wanted to mention that a 100 watt light bulb seems like too much for only a 20 gallon tank. What type of thermometer are you using to check the temps? If you're not using either an infrared temperature gun or a digital with a long wire & probe end, then you're not getting accurate temperatures. Any type of stick-on can be off by as much as 20 degrees.
Can you move his vine closer to the basking & UVB light a little? It seems to me that if he was too cool, he would be staying in the basking area more so I'm not sure that increasing the temps is a good idea at this point. Please fill us in on the thermometer you're using.
You should also be feeding him greens/veggies every day. He may not eat much but it should be available at all times in case he wants to nibble on them. Here's a site that shows the best ones in green print: http://www.beautifuldragons.503xtreme.com/Nutrition.html
Since you have been changing the bulbs around, it would be a good idea to bathe him more often to make sure he is well hydrated. A bath in warm water tested by the inside of your wrist for about 15 to 20 min each time should help with proper hydration. Make sure to put a cloth down in the bottom of sink or container to help him feel more secure and to keep him from sliding around.
Getting a fecal sample checked for parasites is a good idea. Please keep us updated on him.
