I have to disagree in some part with the above replies. If she is healthy and sound, there is no reason to expect less of her because of her age. And honestly, at her age, there is no excuse for bad ground manners, especially because she should have "been there, and done that." With her age, it is possible that she has been used for beginners, and she has learned to get away with things.
Though I am not a full on Parelli follower, I would say that his level 1, seven games are a great thing to do with your horse, they are interesting and improve ground safety and manners.
You could also do ground driving and lunging with side reins.
I also think you should continue to add in little five minute sessions of the basics (walk, trot, stop, back).
Remember, if you are getting bored and frustrated, you horse probably is too. :)
Have fun and good luck.
