I fear I'm too dumb to use save editors. But I guess if I gave someone my save file, I would let them do it.
You don't need to. To get Breeding Papers 3, all you need are Breeding Papers 2, which you can get from Clemont with high enough Depravity (around 20 I think). There you have fuck a horse, and they give you BP2 without needing BP1. For the money, either keep doing jobs or just use the in-built cheats to give yourself lots of money.
