You may also want to join the "New Player" servers when the game comes back up. Unless you got a bunch of cool stuff. Since you said you haven't played in 2yrs though, you probably missed all the cool items and character data. Still keep all your stuff as you will need the codes and your SE account to get your free ARR download, otherwise you will have to buy it again.
You probably want to DL the Benchmark and enjoy the scenery: HERE!
You might also get lucky and get into the Beta by signing up: HERE!
