Brown dry scales on my new ball pythons belly??

There are experts on this site; i am NOT one of them, in fact i've only had my snake for a few months. But i have pored over care-sheets, forums, and other sources of info before and since getting into the hobby so please take my suggestions for what they are worth.

First and foremost, get those pictures working; there are amazingly knowledgable users in this group but there is little they can do without actually seeing the problem.
As far as waiting on feeding, if he actually ate for you right after you got him home thats great albeit surprising but you handled him WAY too soon after he ate. Not sure how big he is (again, pics please) but after 2 mice give him 72 hours minimum, more would be better. especially since you don't know his feeding habits yet and considering he regurged about 48 hours after you fed him the first time. Further, if he regurges, wait a few days before attempting to feed him again - his poor little digestive tract is traumatized.
Until you have this belly scale thing sorted out, i'd use a layer or two of white paper towels for bedding; it is very non abrasive and also shows evidence of shedding, excreting, mites, etc very well. But it does not hold moisture well which is good if rot is an issue, but the ambient humidity still needs to be correct so mist lightly until you get it where it needs to be. Incidentally, you'll never get the humidity right with just a screen top; there are lots of tricks, but a quick fix would be to cover it with a moist towel (except for where the lamp is, of course) this will still let air flow but will retain heat and humidity well.
Get that UTH on a thermostat NOW. don't trust your touch; your body is 98.6 degrees, so hot and cold in the range of 80's to 90's is far too subtle to determine with your hands.
For now i'd say leave him alone as much as you can. If you need to move him to adjust his tank, do so quickly and gently. Same if you need to inspect his troublesome scales, but don't "play" with him for a while (i know its hard to resist), it sounds like he's having a rough time right now and needs to settle.

This is going to sound mean, but it doesn't sound like you're quite ready to be a ball python owner. These snakes, while they are easy to take care of after their setup is near perfect, it takes time and a decent amount of money to get things set up correctly. These snakes are fairly hardy and tough, but you've already got a few things going against you. Did you get him from a pet store or a breeder? I would maybe talk to them and see if they can keep the snake for you for a week or two until you are able to get all of the husbandry (tank) issues corrected and under control where they should be. Here is a good link with a TON of information that will provide helpful to you. Read through all of it if possible.
