So I take it that you're going with Books? I'd definitely recommend looking at some of the lower-penalty Rituals from the Path of Protection; a magician who knows how to influence others but not how to keep himself and his friends from being influenced isn't likely to last very long. Beyond that, it really depends on what kind of magical tradition the primer is for: a hermetic tradition is going to teach different basics than a wiccan-style tradition, which in turn will differ from something voudoun-flavored.
