Try to do what ALegUp said- sit deeply, and make sure you have contact with her. Relax, concentrate on what you want to do. If this doesn't work, take her down to a walk, quiet her down, and slowly work up to a gait. When she acquiesces, reward her by releasing some of your pressure on her. If she tries to speed up again, start the process over. I had to do this with my MFT mare and now she only trots when not being ridden. It may take some work.
I would try to work on the issues separately. Start by trying to change your horses mindset of needing to be in front all the time. Then, work on the gait issue separately and away from a group.
You have to learn how to fall before you can learn how to ride~
