Wow. I really wish you had come here for advice before buying the snake, I think we could have saved you a lot of money.
First, did you get a thermostat (not thermometer) for those lamps to regulate them so that the enclosure doesn't overheat? If not you left out the most important piece of equipment.
Second, you need two hides, one on the cool side and one on the warm side, so your guy can thermoregulate. Ball pythons are naturally shy snakes and they like to burrow and hide. The hide should be just large enough so your snake can squeeze into it. Stay away from the wood log ones with two open ends, they are crap. Personally I use food containers with a hole cut in them, they cost next to nothing.
Using cypress for substrate is good, it will help with humidity and unlike aspen you can get it sopping wet and it won't mold.
You also need to make some sort of a solid top that goes on top of the enclosure to keep heat and humidity in it. Short-term you can cover it with something like Glad Press n Seal, just leave openings for the heat lamps. Long term you can make them out of plexiglass or wood.
I would also add a big water bowl to help with humidity.
