I'm pretty sure the crit percentages in the stat screen do include talents really. Because I remember me actually checking that to find out if I had to get an addon for that or not.
This was about a year ago, and I can't imagine this being removed from the game?
EDIT: misread the question, sorry, I'll be a good boy and look for an addon now.
EDIT2: it's updated on Curse.
