I'm heading out shortly, so unfortunately I don't have time to be thorough right now but read through that and caught one GIANT red flag...
You need to follow very strict quarantine procedures when bringing any new reptile home. Since your two snakes are side by each you need to seperate them into seperate rooms and start a strict 90+ day quarantine on BOTH animals now.
You'll want to seperate them ASAP and begin the quarantine process ASAP.
