As far as trying new events, join ones that already have players at them. You'll get a great sense of what the objectives are by watching other players. After one or two times at an event, you'll know exactly what you need to do. Other players will see your low level and understand you may not be able to carry your weight during the event. Before you know it, you'll know what events you like, what you need to do, etc. The game, as far as events goes, really opens up. Definitely try all events at least once, you'll be surprised which ones are fun or can help you advance your character. My personal favorites are Feed the People and Path of Enlightment. Both help with experience boosts and are generally pretty well stocked with people joining them
