These files are not geospatially enabled though. These files would be in
EPSG:404000. I got around the other issue I've been having with EPSG:404000 by
configuring EPSG:32662 instead.
Should I continue this practice and fool Geoserver into allowing me to upload
these kinds of files? Of course, these files will have bounds that greatly
extend past the normal Lat/Long boundaries if I do this...

Hum... I guess that in order to retrive meta-information about the file at some
point the file is fully decompressed into
memory.
PNG is possibly the worst raster format I can think of in terms of performance,
in order to read even a small portion
of it it has to be fully decompressed and loaded in memory.
Save yourself a lot of trouble and use gdal_translate to turn these files into
GeoTiff ones, eventually internally
compressed (DEFLATE if you want to avoid quality loss)
Have a look at this presentation:
