HOWEVER....

It was also mentioned, when the akatsuki were using their combined chakra for that giant demon extraction jutsu, that the process would take much longer with the absense of orochimaru, which wouldnt make sense if there were the same number of akatsuki members back then as there were after oro left. Unless the difference in chakra between oro and deidara is vastly significant. Also, this means they had to have an extra ring lying around, because oro still has his.
I think the extra time mite be due to the fact that oro knows an immense amount of jutsu's. Its possible that he was either better at that extraction jutsu, or that he knew some other jutsu's that would make the extraction go faster. Also, he probably does have more chakra then deidra. I've always thought of oro as the second (or 3rd) strongest in akatsuki. The only one oro is afraid of is itachi, so its reasonable to assume that thnks himself stronger then the rest of the group.
That doesn't explain the odd number of rings.

As for the unsealing thing, i think kabuto just thinks sasori unsealed him. We know that sasori had some mindcontrol jutsu in his arsenal, and we also know that oro and sasori used to work together. I think that oro originally recruited kabuto in konoha, and when he left akatsuki, sasori used that mind control jutsu on kabuto making him think that he had been freed or whatever. If kabuto thinks that sasori helped him escape from oro' grasp, he'd probably want to repay him by spying on oro.
We know that sasori had some mindcontrol jutsu?
