Seat of Knowledge is the archeology trainer for Pandaria–you’re looking for the very out-of-place dwarf by Lorewalker Cho.
Not sure where the one in Ashran is, but the Dalaran one is probably New Dal, just because archeology is newer than Wrath. The archeology trainer is…either in the mining place, or next door to the obliterator.
No, because the archeology trainer isn’t there.
