It is true, I've managed to gain a few FP with him while level grinding. The enemies with the highest chance to gain FP with Iggy are the Overdrives, you can identify them from the other automatic Stands by using the radio, if the enemies don't disappear, then they are indeed Overdrives. Their movement patterns are also different than the regular enemies, they will try to move away from you instead of towards you most of the time.

As for the Secret Book Vol. 12 (I assume you mean 12, they don't drop Vol. 11), the chance is quite low, I've managed to get quite lucky, but my friend who has played the game three times has never managed to get it to drop once, so don't feel too bad. You can buy them in the developer's room after beating the game for 100k for use on your next playthrough, if all else fails.
