So I'm not so good when it comes to tracking down elusive rules, and I'm making a Gunslinger and am trying to interpret these documents.

According to the Pathfinder Society Roleplaying Guide Guide:

Ranks assigned to Craft skills are used only to perform Day Job checks, not to craft mundane items, with the following exceptions.

• Alchemists can use Craft (alchemy).
• Gunslingers can use Craft (gunsmithing).
• Investigators can use Craft (alchemy).

According to Additional Resources:

The following two feats function differently in Pathfinder Society Organized Play than they do in regular games:

Gunsmithing does not grant the ability to craft firearms, ammunition, or black powder. Rather, it allows the purchase of bullets, pellets, black powder, and alchemical cartridges (with 1 rank in Craft [alchemy]) at the listed reduced price, but does not grant a discount on the purchase of any firearm. Resold items gained through this feat are worth half the actual cost paid, not half the regular market value for the item. No PC can purchase a gun without this feat, even if they possess the Amateur Gunslinger or Exotic Weapon Proficiency (firearm) feats.

I think it is worth noting that Additional Resources only refers to the FEAT of Gunsmithing, not Craft (Gunsmithing). If they wanted this to additionally cover Craft (Gunsmithing), they should have added it to the feat description in Additional Resources. To me, the feat is only intended to allow non-Gunslingers to purchase firearms and firearms accessories. Additionally, the feat Gunsmithing, plus a single rank in Craft (Alchemy) already allows the Gunslinger to purchase all necessary ammunition for the same price as crafting it.

So. What does Craft (Gunsmithing) do for Gunslingers? Or is only intended as a means to create ammunition should an appropriate merchant be unavailable?

In the Alchemy Manual there is an entry for making alchemical ammunition. For example, the Raining Arrows that deliver Holy Water splash weapons.
Since the text states this can be applied to ranged ammunition that does piercing damage, could I apply something like the Raining ammunition type to a blowgun dart? According to the text these should be allowed, but then I picture a Trip dart fired from a gnome-sized blowgun.

Quoting from the new Additional Resources document published August 10th, "Class Bonuses: The favored class bonuses in this book are legal for play except the gathlain’s kineticist favored class bonus."
From my interpretation of this, the other Gathlain favored class bonuses are legal. But the Gathlains themselves are not society-legal?

Additionally, Additional Resources says all Additional Racial Traits and Feats are legal, and doesn't list the Gathlain material as excluded.

Are there any Gathlain boons, am I missing something, or is this a hint at changes to Season 9?

I've only been playing Pathfinder since March, and there is a lot of material spread out all over, so it's entirely possible I've missed something.

The other night the Venture Captain told me that I could only purchase one thing at a time using Prestige points. I had made multiple purchases of vanities, not realizing there may have been a limit.

Checking the guild guide, on page 22 there is a reference stating that a GM can limit the spending of Prestige if it obstructs gameplay, making it sound like Prestige can be spent multiple times.

The Venture Captain pointed out that on page 21, there is a note that only once per chronicle may you spend 2 Prestige to purchase an item worth 750 gold of less for free.

As I'm purchasing vanities (such as multiple vanity followers, titles, and businesses) and not items with an explicit gold value, I don't see this as applying to the free item purchase limit.

Any thoughts?
