Alright, I've gotta go do stuff today, but I should be back on later.
For now, enjoy a sorted list of players - it certainly helps me think it through.
I've also included roleclaims and my thoughts on them.

[M] Wedge - Oracle (possibly confirmed by Balthier's whisper, conflicts with Penelo's claim)
[M] Leon - No claim
[M] Luneth - No claim
[M] Rydia - Apothecary (possibly confirmed by saving Cid based on Faris' observations - Highly plausible given poisoner and lack of other claim on apothecary)
[M] Faris - Watcher (possibly confirmed by saving Cid - not sure if Cid was actually targeted, could have been a distraction)
[M] Cid - No claim
[M] Wakka - No claim
[M] Rikku - Gunsmith (nothing to confirm or deny - everything checks out, and Relm was a Mafian with a gun...)
[M] Penelo - FBI Agent (nothing to confirm, and conflicts with Wedge's claim)
