All sounds good!! You'll be a great snake parent!!
As for the drinking, I think that's perfectly normal. If she was thirsty before eating she may have just needed a bit of hydration to help move her prey down.
They got the majority of their water from their prey, so don't drink all that often.
But I certainly wouldn't sweat her drinking. She knows what she's doing.
Keep up the good work and feel free to ask all the questions you may have. We're happy to help.
