Ana,

To import tiff images, you canuse r.in.gdal (just use 'r.in.gdal help'
for a small explanation of the arguments). However, you have to be
sure that all files are in the same projection (use gdalinfo for that,
and reproject with gdalwarp if needed)

Good starting point for brazilian data:

http://www.relevobr.cnpm.embrapa.br/conteudo/projeto.htm

World data (elevation data, satelite images, etc...)

Also, be sure to browse grass.itc.it and the list achives, there is
gold in there!!
