Hallzy, ACTION not WORDS. Don't tell her anything. Just act.
When she calls, don't answer. If it is an emergency she will leave a message that you can check,.
If she texts, don't respond. If it is a direct question, that you feel you must answer, short answers. Direct to point. Yes or no questions get yes or no answers. If it is a direct question that you don't have to respond to: "How are you?", just ignore it.
I like your list. However it is NOT in the correct order:
1. IC for her or an equivalent that helps deal with immense baggage: self harm, anxiety, codependency, controlling behavior, depression, father not present, Mother alcoholic enabler. 2. MIL cannot live with us again 3. MC 4. Full transparency
Make #1 a requirement before you would EVEN consider taking her back. She has work to do on herself.......make her do the work.
