She needs to learn how to respect you first...don't coddle this horse; teach her that YOU are her leader, or she will continue to test your authority. A horse that kicks and bites like she sounds like she does, is a horse that is basically telling you "move it, get away from me, don't touch me, etc..."
Start taking her out of the barn to do your grooming, tacking up, etc...maybe a round pen if you have access. Every time she gets snotty on you, make her move her feet; yield her hips, back her, lunge her, do sending exercises, etc... every time she wants you to stop what you are doing, move her feet, and make her work (the harder you can work her, the quicker she will catch on that being 'quiet', and complient, is the best answer.). Keep in mind, she may take longer to grasp the concept, simply because you are not the only one handling her, and she may never be fully trustworthy (again, due to the inconsistancy in handlers). But with some time and consistency on your part, she should start to realize that you aren't going to accept her behavior.
