For example, if you cast Align Weapon with the Good descriptor, does the weapon gain an alignment of Neutral Good? Does it gain an alignment at all?
I would say yes, it does; it makes the weapon Good, it makes the weapon aligned, and I've already shown why I believe a weapon that is aligned is a weapon that has an alignment.
Is gaining the Good descriptor the same as gaining an Alignment?
The spell has the Good descriptor, not the weapon.
Or must the weapon and/or ammunition both be intelligent for an actual alignment to apply (if one assumes that Holy weapons are aligned, but do not have one of the 9 alignments)?
Alignment doesn't require intelligence; compare the skeleton.
Holy is not defined as Neutral Good. It is also not defined as an alignment at all.
A Holy weapon is good-aligned. Under the premise I've given (that a weapon that is aligned is a weapon that has an alignment), it woud have an alignment that is good; that is, one of the three, LG, NG, CG. In the absence of anything making it Lawfully aligned or Chaotically aligned, it would be Neutral Good.
Holy is defined as Good, but Good is not one of the nine alignments that you stated all weapons with alignments must have in the quote above.
Indeed; rather, it is three of them.
What happens if you have a Holy Weapon with Unholy ammunition? Anything?
As I said earlier, I seemed to recall this being a sticking point last time.
If we fire a normal arrow from an intelligent, Lawful Evil bow, it is ammunition fired from a projectile weapon with an alignment. Thus, the arrow gains the Lawful Evil alignment.
If we fire a normal arrow from an Holy bow, I maintain that it is ammunition fired from a projectile weapon with an alignment. Thus, the arrow gains the alignment of the bow - Neutral Good, in the absence of any factors other than Holy influencing the bow's alignment.
If we posit the existence of an intelligent arrow (I don't believe it's legal under the intelligent items rules, but let's assume for the moment that it is), with an alignment of Lawful Good, and we fire it from an Intelligent, Chaotic Neutral bow, it seems by the wording of the passage you quoted that the arrow gains the Chaotic Neutral alignment in addition to the Lawful Good alignment it already possesses. I'm not entirely certain how this works - how one entity can possess more than one alignment.
