If the temperature is in mid 70s, that's still not too bad but you want to make sure that you have a digital thermometer on the cool side so you can monitor the temperature. You can pick one up at any hardware store for about $10-$15 bucks that will read both temperature and humidity. Once you figure out what your ambient temperatures hover around, you can decide whether you need an additional supplemental heating lamp. I also PM'd about some stuff I have for sale if you're interested.

In regards to the cleaning, no need to use soap if you're going to get the Healthy Habitat. I usually take everything I'm intending to clean out of the enclosure and put it in the sink or the tub. Then I spray the cleaner and scrub whatever needs scrubbing with a sponge. Then I rinse and put it back. I don't trust myself mixing chlorine or any other harsh chemicals so even though there's probably cheaper alternatives, at the end of the day I know that my snakes will be ok.
If there's multiple stuck sheds, soaking might not be a bad idea but as someone already mentioned, by soaking your Ball Python, you're washing away essential oils they use to take off the shed. If you keep your humidity up, they'll usually shed by themselves. There's definitely different ways to help your snake shed including the pillowcase method and others. You'll just have to experiment with whatever works best for you. The only thing I must warn you about is the eye caps. Don't try to take them off yourself because you might accidentally injure his eyes.
Since you have a screen top, you can close off at least 2/3rds of the terrariums screen without sacrificing ventilation. When I had glass terrariums, I used plastic squares that I put on top of the screen so the humidity doesn't escape as fast.
By the way, if you have a smartphone, dowload Tapatalk for the forum. It makes things much easier.
