The manuals:

1. From the guy in the room left of the cloister stairway in Djose Temple.
2. From the guy just outside Experiment's room in Djose Temple. Password: MARNELA.
3. From the monkeys by the interview office outside Djose Temple. Press X when all three jump simultaneously.
4. From a machina near the northern Mi'ihen gate (haven't figured out how to get it).
4. From the Ruin Depths Chocobo Stables secret dungeon (have yet to open this dungeon).

As for Experiment parts... Beat him once before his stats are 5-5-5. Repaired it with the first repair manual. Afterward, I did 30 digs (total 45) in the Central Expanse (previously had 15 from the Western and Southern Expanses) and the stats were at 5-5-5. Cat Nip for an easy kill.
