Tim covers things well. All the Penny Dreadfuls (multi session adventures) and one shots are available on Drivethrurpg if you don't mind pdf's. One-shots are only available via pdf.
The character fates and progression is the only section I feel need more explanation. The game is meant to be a fixed-length campaign with a number of sessions equal to the number of players times 5. There are 5 steps to each character's fate and each session is in tented to resolve one fate step for one character. This puts each character front and center of the storyline for that session. Not sure if your players are looking for that kind of game or not. If not, there are ways to work out progressions and lengthen the campaign. Let us know if that is the case.
