I know there's already a stickied True20 errata thread, but I haven't been active in it for a couple years now, and True20Chick has informed me that she had no errata for the three role handbooks. So I'm going to post this here for now so I can find it easily when I'm ready to add to it.

I have the fewest notes for the Warrior's book, so I started there. I just need to type up the others, so I hope to be able to post those links over the next few weeks.
