Because I know something you don't known - I am not one-handed!

a) Is switching from a one-handed grip on a weapon to a two-handed grip on the same weapon a free action or a move action?

b) If it is a move action, can one do it as part of a regular movement if one has a BAB of +1 or higher?

c) Does a 5' step count as regular movement for the purpose of drawing a weapon if one has a BAB of +1 or higher?

d, e, f)) What about all of the above but for switching from a two-handed grip on a weapon to a one-handed grip on the same weapon?

Free action as per the FAQ.

c) Does a 5' step count as regular movement for the purpose of drawing a weapon if one has a BAB of +1 or higher?

I don't think so.

d, e, f)) What about all of the above but for switching from a two-handed grip on a weapon to a one-handed grip on the same weapon?

Yes.

Agree with Dandu on all points. Although, "FAQ says so" would not be a valid reason to me.

 

[Dandu]

I'm willing to listen to the FAQ when they're not contradicting the actual rules. (This isn't explicitly covered in the rules.)

Free.

No.

d, e, f)) What about all of the above but for switching from a two-handed grip on a weapon to a one-handed grip on the same weapon?

D) Free. E) Null question. F) What's the question?

Free action. In fact, some spells or invocations would not work if it required an action. Since the GM is free to limit free actions, I think more than two grip changes per turn would be pushing it.
