1) Squall going into space in no way helped Ultimecia. Ultimecia was using Rinoa to free Adel, Squall very easily could have stopped her if he tried (he didn't because it was Rinoa, but Squall has defeated a sorceress before). And Squall being in space only served to rescue Rinoa so that she could live to fight Ultimecia. Had Rinoa died, it wouldn't have mattered to Ultimecia after she performed time compression, she would have received her power anyways.

2) Edea went to Odine of her own free will to try and repress the powers she still had. She was willing to do whatever it took to be free from possible possession by Ultimecia again, even if that meant being locked in the Sorceress Memorial. None of this would have in any way aided Ultimecia.

3) I was under the impression that the Mobile Type 8 stopped Zell's pursuit into the Lunatic Pandora, which I imagine was put there by Seifer, knowing that his Balamb Garden friends would probably come and try to stop him.

Edea was weak after her fight with the SeeDs, and nothing that Edea did during disc 3 in any way would have aided Ultimecia, so I can't see how she was possibly still possessed. Not to mention, if she was still possessed I don't think she would have given the scoop about her master plan to Squall and company.
