Unfortunately not. I never played with raster italian data, believe it 
or not, my data experience is only with freely available USA data.
Can you provide us a sample by private mail? Also, which version of 
Geotools are you using? I suggest to checkout and compile 2.3.x branch
if you haven't already done so. Raster support in 2.2.x is rather poor,
and quite a bit of improvements got in 2.3.x after the 2.3.0 release.

Well, since there is no way to tell whic CRS is it, it's a guess
that's as good as any other imho. Most data coming from NASA and similar
sources in in fact unprojected WGS84 data.
