I haven't played Changeling in a very long time and I don't have my books available ATM, but I am confident telling you that specialties refer to your choice of player-defined modifiers that apply when you are using that skill in a specific way. For instance, if you want your character to be really good at shooting with revolvers, you can choose Firearms [Revolvers] (revolvers being your specialty). If you want your character to be really good at stealing cars, you could define your specialty as Larceny [Grand Theft Auto] (using larceny skills to break into and stealing cars). As far as what can be a specialty is up to you as the player. Sorry I can't help with the Glamour question ATM.
