You are correct, EXTENT should be in the MAP projection, however that isn't usually the problem because GeoMoose passes in its own extent that overrides the one set in the mapfile.
I presume that is a shortened mapfile to only show the projection parts and the real mapfile is longer.
You can reproject your extent using the cs2cs tool that is part of the proj4 package (which is almost always already installed if you have mapserver).
Assuming you have proj4 and bash (shell) installed
cs2cs +init=epsg:32748 +to +init=epsg:3857 <( echo 681064.622758 9296398.489077 ; echo 696909.822267 9311182.143822 )
11870774.49 -709769.35 0.00
11886665.80 -694745.80 0.00
Alternatively you can type/copy in the coordinates, when you press enter it will respond with the reprojected coordinate.
cs2cs +init=epsg:32748 +to +init=epsg:3857
681064.622758 9296398.489077
11870774.49 -709769.35 0.00
696909.822267 9311182.143822
11886665.80 -694745.80 0.00
So:
EXTENT 11870774.49 -709769.35 11886665.80 -694745.80
