Finding people to spar with is a great thing, and like Matt said finding a style to work with and practicing it works wonders as well. Take the skills you're coming into game with and look for movies and instructional videos on how to use them better. Sword and shield for example, look up SCA combat videos as they're a heavier version of boffer combat. Watch other people's movements, don't just watch their upper torso, footwork is just as important as anything else.
