Okay here's the whole situation:
It appears that when racials went in, some ended up only being added to work against other clients, as opposed to NPCs; A small oversight which is easy to make based on how damage is handled. This will be corrected next patch.
As for the effects of innate, AA, and worn crit chances, none of these require each other to function. Innate bonuses to crit always work, worn Critical Strike on gear is scaled to the recommended level of the gear in relation the character, and AAs always work as long as you've purchased said AAs.
