An alternative approach is to approach her via text, and say I'd really like this to be a team effort and I would appreciate your input. Then schedule a time for a private get-together, lay out your plans and goals, ask her about hers and try to work some in. Make an effort to recognize her talents, rather than her drawbacks. (There must be some talents there)
Really make an effort to befriend her, and to let her get a piece of the action. Let her find out how difficult it is and help her learn, rather than try to get rid of her. If she stomps on you, then you can stomp back, knowing that you tried. Obviously she has talked to the boss. So try the honey approach first, and if needed, move on to the vinegar. Teach first, punish later.
