Enjoy the first 12 hours, ignore the last 30 minutes until they actually start. Write out the things you want to say, refuse to be interrupted, just keep talking and giving report. If they interrupt, hold up your hand and keep talking. At the end, ask for questions with a smile. For questions, repeat, "I told you that..." and repeat exactly what you said to begin with unless its a legit question. For eye rolling and sighs, ask if they are feeling faint and need to stop? or shall we go on with report? Then keep talking.
If they can be "that's how they are", so can you: concise, calm, unflappable, solicitous and thorough.
Sounds to me like your manager needs to sit in on report and control some of those behaviors herself, IMO.
Have a great time in that new house of yours!
