In your chat window type /waypoint followed by the location numbers. Or /way for short. You'll get a red dot on your map if the loc is on that part of the map (Some zones have more than one window worth of map), and you'll get general directions in your chat window until you're close enough for the "magical path", an ethereal glowing trail, to show up and guide you in.
Be aware that many loc's are "close enough". We try to stand right on the spot for an loc, but sometimes that gets you dead (haha!) or the mob wanders a bit.
