Carlo,

Generally speaking when loading non-8bit data you will want to apply
some sort of scaling.  I would suggest you read the section of the Raster
HOWTO on scaling non-8bit data, but the quick thing to test is to add:

  PROCESSING "SCALE=AUTO"

in your layer definition.

No, there is no support for .lyr files.  Generally speaking you will
need to define a bunch of CLASSes with colors for different ranges
of your field.  This is also covered (briefly?) in the raster howto.

Good luck,
