Although I believe the 10:28 (08:40 from Newcastle) stops at Haymarket on its way to Aberdeen, which is one of the other stations in Edinburgh. The majority of buses (including some of the mainstream services) stop at Princes Street which is the main bus area in the city I gather, and located very close to Waverley station.

Very close indeed. If you exit the station at Waverley Bridge (the only exits i think), which is where the Airlink 100 and Tour Buses terminate, turn right and go to the traffic lights - that is Princes Street. Shouldn't be too difficult to find.
