Yes i got the Nar Shaada aim datacron. The Kiosk moved at a snails pace. Get on the bus stop and look around for anything moving. Its a circular pas with adverts on it. It moves around the whole zone, so look for any movement.
As for blue matrix shards, there is the one in the heroic area on Hutta, the one on the sand crawler on tattooine, and the one in the labor valley on Corellia (which triggers a codex entry for quesh)
Is this the one that can be reached by a lone air taxi that you get to by jumping down to it, then riding that over to the kiosk?
