I think you are both right in a sense. I think that Kaneki captured Eto so that he could raid cochlea. Why? If Eto was still on Rue island then Kaneki would have to go to Rue with everyone else and he obviously wouldn't be able to raid cochlea if he's on the island. Either Kaneki or Arima would have to go to battle Eto since no one in the CCG is strong enough other than them and there is no way they would trust Kaneki with cochlea. By default he would have to go. There is also no way that he could successfully get Hinami out at any other time due to the sheer amount of forces (including his ex-students who would then have to fight him and/or watch Arima kill him) that are at CCG at any given time except in the case where most leave for Rue island. That's why he was in such a rush and was saying that time was of the essence. He had to get Eto into cochlea before CCG planned to send him to Rue.

I agree that I think he was surprised that she saved his friends; he's not stupid he knew she wouldn't just come quietly and had to have a way to escape but not that she would directly put herself in great risk and die to save his friends. As for Ayato, maybe he knew about that, maybe he didn't. Someone gave him the key card and it could have been Arima who gave it to Eto who then gave it to Ayato (after Arima has been revealed to be OEK and knew Kaneki would need help if he was going to survive this). I don't think he would have been directly involved with that exchange though because it's too risky to be seen talking to a ghoul if he wants his plan to work and he seemed surprised to see the re: group (slightly my interpretation I admit becuase there is no way he would put  the re: icompany n a place as risky as cochlea. That sounds like something Arima and Eto would do though as bait to get Kaneki to try to survive. Ayato recruited them but Eto likely knew.
