See my edited original question for how I made this work.

comment How to sort legend values efficiently in QGIS print composer?
I've tried sorting the values in a saved qgis color map, but that isn't doing the trick.

comment How to duplicate this QGIS workflow with gdal/GRASS? (reproject and crop a raster)?
That is not the behavior I observed when I did not specify a target resolution. Rather, the target resolution was significantly lower than the source.

comment Where do I find the code for gd_calc.py?
Thanks for writing gd_calculate. That is likely the answer to my real question, of how to average large numbers of rasters.

This question is clearly a duplicate of the one that you linked, Jay. I don't know how I failed to find that, as I did look.

comment Error message starting gis.m in GRASS
Thanks, Gene. I see no reason to use the older unsupported GUI. I'll just have to figure out how to deal with aspects of the book that are out of date. It is very frustrating to pay $85 for an eBook that is out of date, however.

comment How to script map production in GRASS?
Thank you! I think you're answered my question, but it'll take me just a little bit to work through what you've provided.

comment Error from ps.map in GRASS. How to fix?
The command "r.info rastermapname" returned the expected information about the raster to the terminal, with no warnings or errors. It did not "bring up the interactive gui." It's not clear to me that it should have, however. Perhaps I misunderstood your previous comment. Should we move this to another forum? I'm content to keep this here, if it's the appropriate place.

comment Data management in GRASS from command line?
For others interested in learning about data management from the command line in grass, look up the documentation on the following commands: g.mapsets, g.mapset, g.list, g.gisenv, r.in.gdal, v.in.ogr.

comment Error from ps.map in GRASS. How to fix?
I'm not entirely sure how best to test that. Could you please suggest a specific command for me to try?

comment Why can't I load more than 12 elevation files into NVIZ?
I don't think that I want to use the color parameter, as I want to visualize the data in the rasters as an animated time-series of elevation models. There is no real DEM involved (unless you count the rasters that I want to visualize as such). Because R=G=B for all pixels in images, it made sense to me to use a single channel.

comment Why can't I load more than 12 elevation files into NVIZ?
I goofed; the elevation parameter was not actually used twice (just tried again to be sure). I've corrected that in the post.

comment How to set/save the extent of a map in QGIS?
I'll check that out, as it might work for me since I'm not interested in the on-screen animation from directly within QGIS, but rather I'm just using it to create the frames that I'll assemble with some other tool like ffmpeg.

comment How do I tell GRASS where to find Python?
Thank your for such a thorough and thoughtful answer. I might recompile GRASS myself after the deadline I'm currently working on has passed.

comment Data management in GRASS from command line?
Thanks for teaching me a new bash trick, I only knew how to do that with basename. Did you mean for it to trim the tif suffix (rather than .shp), since that should be the only suffix the loop sees?

comment Data management in GRASS from command line?
I understand everything you've done there, except ${file%.shp}. Could you explain that for me?

I edited the post to include the terminal messages on GRASS startup.

comment Error from ps.map in GRASS. How to fix?
Just noticed that the GRASS version I installed from kyngchaos is known to have issues with the Python GUI in Mountain Lion, but it says that the command line modules should work fine. Ref: kyngchaos.com/software/grass
