Neither of those are really secret.
However there is plenty of those, not sure all would fit into the good guy side tho.
Alcaz Island, the Island south of Tanaris, little farm in the far Southwestern Kalimdor.
Pretty sure there is a list of them aswell somewhere..
I strongly suggest you mount up in game going around all the major quest hubs for the faction you are going to be RPing as. You'll be surprised by all the small "secret" alcoves the game designers have put.
