Ray,
The size of the tiff file is ok, and it's mapserver job to resample it to
your smaller window.
I notice that your LAYER definition is a little terse. You may need to
include a NAME and STATUS:
LAYER
NAME "MyLayer"
STATUS DEFAULT
DATA "./data/PAGE48.TIF"
TYPE RASTER
END
You may want to test out the map file using MapServer's shp2img command line
program (http://mapserver.gis.umn.edu/utils.html)
