If you plan to use the mass combat rules Ultimate Campaign is invaluable and you might want to look into Ultimate battle and Ultimate war from legendary games. Pathfinder Campaign setting: The worldwound helps fleshing out the area once the pc's get there in part 2 of the AP. Pathfinder campaign setting: Paths of prestige have details on several prestige classes in the AP notably the Riftwarden and the Blackfire adept. Pathfinder campaign setting: Gods of the inner sea offers plenty of info on Iomedae and the other religions found in the AP and Pathfinder campaign setting: Book of the damned 2, lords of chaos offers plenty of useful stuff regarding demons. There's also the Demonslayer archetype from inner sea combat.
I personally also use most of the mythic stuff from legendary games and kobold press' deep magic. I just recently started to use the leadership handbook from everyman gaming to replace the leadership feat and enhance some of the stuff from ultimate campaign.
Hope this helps

The AP repeatedly talks about "mythic" so you should probably make sure you have that.
Abjuration is good for wizards, nothing quite like spells that make outsiders go foof. A low-ranking demon with teleport as an at-will ability and (possibly) dimensional agility is a nasty enemy to fight. Someone has GOT to have Knowledge planes and knowledge religion.
The everflowing aspergillum is an excellent weapon, but the GM has to rule whether or not its enchantments can be improved upon. If it can't it will eventually be outclassed. (pretty sure the rules deliberately say "GM's call, we don't care.")
An entire party of druids or clerics might be interesting, they'd be weaker than a "proper" balance of classes, but there's something to be said for an entire party that can all turn into birds and wish to "close the wound in the world."
On the monster side I honestly don't know what the AP has specifically in store, but it seems like ways of hiding alignment would be paramount. I know demons are involved by apparently so are cultists and infiltrators? There may be abyssal politics where demons and devils go at it or manipulate one another.
Faiths of Purity and Faiths of Corruption might have some useful stuff, but try to remember there's a stack of books heavier than my sofa to use. It isn't "what can I do" but "what do I want to do in the infinite realm of possibility?"
Oh yeah, read up on the demon-lords involved, there are at least 3 mentioned by name in the AP descriptions, be a good idea to know who they are, what their general deal is, and what evil horrors they made their home realms look like. Baphomet, for example, is big into mazes, minotaurs, and his creepy-ass girl(?)friend(?).
