Conclusion
OK. So here's the final post with the Sets, Other Options, and Polls. These are the sets I feel were thoroughly discussed and reached ICC consensus on.
Name: Disruption-Shot
Move 1: Aura Sphere
Move 2: Moonblast
Move 3: Taunt / Encore
Move 4: Parting Shot
Ability: Natural Cure
Item: Life Orb
EVs: 252 SpA / 4 SpD / 252 Spe
Nature: Timid
(The earliest set proposed, which focuses on Dual-STAB, Parting Shot, and a move to disrupt the passive play we did not want CAP to get flustered by.)
Name: 3-Attack Parting Shot
Move 1: Moonblast
Move 2: Aura Sphere / Focus Blast
Move 3: Sludge Wave
Move 4: Parting Shot
Ability: Natural Cure
Item: Choice Specs / Life Orb
EVs: 252 SpA / 4 SpD / 252 Spe
Nature: Timid
(A basic offensive set utilizing STABs and Sludge Wave to threaten Clefable and other Fairy types that remain generally threatening, which are not very prone to disruption or threatened by our STAB options.)
Name: Mixed Offensive Pivot
Move 1: Parting Shot
Move 2: Moonblast
Move 3: Close Combat
Move 4: Energy Ball / Grass Knot / Giga Drain
Ability: Natural Cure
Item: Life Orb
EVs: 204 Atk / 52 SpA / 252 Spe
Nature: Naive
(The anti-Chansey set that takes a more direct approach to finishing off The Blob and utilizes Grass coverage to make up for some of the power lost from needing to invest in Attack.)
Name: Parting Slumber
Move 1: Yawn
Move 2: Parting Shot
Move 3: Moonblast
Move 4: Aura Sphere
Ability: Natural Cure
Item: Life Orb
EVs: 252 SpA / 4 Def / 252 Spe
Nature: Timid
(Yawn's ability to force 50/50's and further increase the threat from Parting Shot was noted as soon as this set was submitted, again utilizing Dual STAB to threaten the metagame.)
Name: Wishful Thinking
Move 1: Moonblast
Move 2: Focus Blast / Hidden Power Ground
Move 3: Wish
Move 4: Parting Shot
Ability: Natural Cure
Item: Life Orb
EVs: 232 HP / 92 SpA / 184 Spe
Nature: Timid
(The Wish set takes a different approach by providing more team support, and making up for its weaker offense by utilizing either Focus Blast for increased damage output or Hidden Power to subvert counters. The set is designed to test passing Wishes along with the stat drops, as recipients will be better able to take the incoming attack.)
Other Options: Flash Cannon, Charm/Feather Dance, Snarl
(Flash Cannon was basically pointed out to be inferior to Sludge Wave, however it does hit slightly different targets and is largely redundant with Fighting STAB. Charm/Feather Dance and Snarl enhanced the stat-dropping potential of Parting Shot, and while there were arguments calling them either distracting or irrelevant, they are options that liken Parting Shot more to Memento and I feel they are a valid way to further explore Parting Shot in the playtest.)

These are the moves I think should go to a poll:
Spikes - Spikes + Parting Shot is itself a very good combination for two slots. The issue with Spikes is not Spikes itself, it's the ability it has to overshadow Parting Shot
in conjunction with other moves. Encore for example allows CAP to set up multiple layers of Spikes (or one at the very least), so Spikes + Encore could overshadow Parting Shot. I don't think Taunt has the same issue because Taunt forces an opponent to attack or switch, but Taunt also shuts down Defog while CAP generally does well against traditional metagame Spinners - heck, it's even faster than Starmie.
Our concept is to make a Pokemon defined by Parting Shot, but I do not interpret that to mean any move which shares the limelight with it inherently violates the concept. Perhaps a combination with Spikes IS the definitive way to make the most potent possible Parting Shot Pokemon. Therefore I'm putting Spikes up to a vote.
Moonlight - Like Spikes, Moonlight has some application with other moves to move CAP into a Stallbreaking roll without necessarily using Parting Shot on the set. I do not consider it nearly as powerful or attractive as other options, however reliable recovery on a Pokemon with a good typing is what it is.
