How can I overwinter potted geraniums in Minnesota?

I have two potted geraniums that I have heard referred to as anti-mosquito or aromatic geraniums. We live in Minneapolis and have been having some late fall temperatures in the mid to upper twenties, so I have moved the potted plants into the attached garage. Other than giving them needed water, is there anything else I should do to protect them?

You will need to keep these fairly warm. They can start to show stress around 50 degrees or so. They will also need extra light. They do not go dormant, so they will die without proper growing conditions. If you can provide a brightly lit room or window, this will help.
