Ari,

.aux and .rrd files are companion files of ERDAS Imagine datasets (whose main
files are .img). GDAL is also able to read/generate .aux/.rrd as overviews of
other raster formats.

.lyr files are ESRI specific stuff (A search lead me to
http://www.lib.ncsu.edu/gis/formats.html ) and GDAL/OGR has no driver for that
one. Would be more the equivalent of a MapServer mapfile, or a QGIS project
file.
