Steeley, get a pistol, a CCW permit and take some pistol marksmanship classes. Some law enforcement agencies offer self defense classes as well. Many cover armed and unarmed defense. I recommend learning both.

As for martial arts ... unless you plan to spend a lot of continued time in a dojo, save your money for a gun instead. Taking a few lessons or even enough to move up the belt system a few colors is just enough to give you the confidence to get your butt in trouble.
