'set gxout value' will display a number at each station location,
'set gxout stnmark' will display a colorized dot. You can use 'set
stnprint on' with 'set stat on' and then GrADS will print a list of
the plotted stations in the command window. This is helpful to find
out if any data were displayed.

No, the default display is global. You must use 'set lat' and 'set
lon' to limit the domain.
