The International Helsinki Federation on Human Rights regularly comments on Central Asia's humanitarian issues. So far I’ve just glanced through the report and the Country Studies for each state look much more specific and useful than the general pages on Central Asia.
One reason the general pages are not as good: domestic policies in the different states really are changing in Central Asia. Therefore, the region as a whole is becoming harder to generalize. That's both good and bad news, since some states are improving and in others, human rights considerations have been nearly trampled to death.
Just as a general aside, many of the non-Central Asian, non-former Soviet Union states have some thinking to do on their human rights records as well. The International Helsinki Foundation has reported on all OSCE states.
