I have this in my Alterac Valley thread just modified for you !
Graveyards:
Open up graveyards in MySQL and add a new column and these are the inputs:
ID = Put 386 and above.
PositionX = .gps in game and type in the value of X
PositionY = .gps in game and type in the value of Y
PositionZ = .gps in game and type in the value of Z
Orientation = 4.0817
Zoneid = .gps and type in the mapID
Adjacentzoneid = leave this 0
Mapid = .gps and type in the mapID
Faction id = 1 = Alliance. 2 = Horde. 3 = Neutral. I suggest putting the north graveyards as alliance and south is horde. Neutral will cause havoc unless for arena's.
Name = Anything you heart desires
Do this with all the Graveyards and you will be fine.
One thing you will need a Spirit healer code is 6491
Now you will have fully functional graveyards ( i have 6 in my AV alone )
remember .serverrestart and then open it back up
