Suggestions:
- not sure if hgt files are supported, but they are likely not suitable to
web
mapping to start with, you'll need a format that has internal tiling and
overviews. Have a look at this presentation for hints on how to do
the conversion:
http://demo.geo-solutions.it/share/foss4g2011/gs_steroids_sgiannec_foss4g2011.pdf
- lump up all the files with the same resolution in a single directory
(so make one for 1 arc second, another for 3, and a final one for 30)
and then configure an image mosaic on top of each. This way you'll
just have three layers
