Haven't found a bus here to Stanley. Usually, it is suggested that you take metro from Yau Ma Tei, where the hotel is located, to Central. And then take bus 6, 6A, 6X, etc at Exchange Square to Stanley Market directly.

Do you mean that you would like to visit the Peak by tram after return from Stanley? If so, you could take the same bus back to the Garden Road, Central and then walk to the tram station.
