The healers move to the Blue Boar inn after the escort quest is done, with just Mardaneus remaining in Aleroth. Lanilor is in the north west room behind the bar and kitchen area, Joram is by the bar and Otho/Goemoe in a couple of the inn rooms. If you progress far enough in the main plot quest, Geomoe will eventually leave the inn, and you will need to talk to the healers and do something else to find where he went.
If you stand, or teleport, next to a teleporter stone, you should easily be able to pick it up. It sounds like you have trouble picking up other items like this (letters, chests, etc).
Do you have any problems drag and dropping in Windows? I once had a left mouse button start to go flaky, where left button presses would occasionally not be recognized, or would register as double clicks (very annoying when you are trying to move 50 files and Windows decides to open them all). It started getting worse, so I took the mouse apart and noticed a notch worn in the plastic tab on the button over the sensor; I filled the notch with epoxy, let it dry, put the mouse back together, and haven't had a problem since.
The arrows are just for atmosphere.
