I'm uncertain, but seeing as Rand's side won that battle, the ter’angreal either made it to Tar Valon, or the wise ones kept them
As for Moiraine and Lanfear... When Mat, Rand and Moiraine went in before, they didn't enter along with a mortal enemy. Lan said he felt the bond with Moiraine break, which is another thing to consider. Also, those Aelfinn and Eelfinn aren't the friendliest.
Oh, and have fun reading the rest of the books. There are a few surprises left.
