Ok, happy to help you out...
1) They prey size will change as the snake grows, but an adult female will take a medium rat (or 3-5 mice depending on size) every 7-10 days. You will have to determine what works best for you and the specific animal.
2) 95 is too hot 90-92 is ideal for a hot spot. 80-82 is ideal for your cool side. Humidity is ideal in the 50-60% range with a bump to 70-80% during shed.
3) BPs do NOT need a light cycle. They don't need a light at all. Whatever light enters the room and enclosure naturally will be enough.
4) Snakes get illnesses, just like any living thing. The best way to prevent them is with proper husbandry, keeping a clean enclosure and keeping yourself clean when handling your snake or going into the enclosure.
5) Frozen/Thawed is the preferred prey. The best way to get a snake who accepts F/T is to purchase from a reputable breeder who already has the animal readily accepting F/T. There are MANY ways to get a snake to switch over, but that's a whole thread on it's own...
6) I would advise researching breeders. See if any are local to you. check out morphmarket.com and look around. You may be able to find some of the breeders near you are going to the local expo. You can always have it shipped. Just do your homework on the breeder and ask questions. But buy from a reputable breeder. As far as reptile/aquatics shops, some are better than others. Many do not breed their animals and are just looking to flip them for a profit, so that will seriously depend on the individual shop, since some can be really good.
7) Read through the stickies on this forum to learn about the proper setups. Study, research and learn. Not just the basics, but learn all you can about the animals themselves, not just how to keep them in captivity. The more you know about the animal and understand, the better you are equipped to provide a proper home.
One thing you didn't mention is a thermostat. VERY important and no enclosure should be heated without one.
Make sure you have ALL your equipment home, setup and running properly and dialed in BEFORE bringing your snake home.
I hope this helps. We are here when/if you have more questions.
P.S. Be careful who you take advice from, and always get info from multiple sources before you believe it. Don't trust one person, especially one person in a retail setting.
