The reasons why Aogiri wanted Kaneki and Rize weren't made 100% clear if I remember right. Initially, it seems to have related to Kanou because he took an interest in Rize who had a unique kagune so wanted her for experiments. When Aogiri couldn't get Rize or Kanou, they settled for Kaneki. They seemed to have known about Rize having a unique kagune and Kanou's experiments, so they wanted to "check the goods" so to speak. Tatara was interested in Kaneki's kakugan and from what I recall (it's been a while since I read the manga, so this part's a little fuzzy to me), but was dissapointed when he saw it was a left one and dubbed him useless. I guess they were hoping that Kaneki would be a powerful half-breed, with unique powers, and a right kakugan, but had brushed him off too quickly.

Considering what we know of Aogiri, I think the most obvious reason for all that was that it somehow related to the One-Eyed King because they had always been depicted with a right kakugan, but what the significance was hasn't been revealed yet.
