See the -projwin or -srcwin options of gdal_translate for the 
subsetting. http://www.remotesensing.org/gdal/gdal_utilities.html

You can use the "-b" option for selecting/reordering particular bands 
but I believe all the bands have to in the same source file rather than 
band1.tif, band2.tif, etc. (I would love to be proven wrong about this)


Somebody else will have to answer about accessing programmaticaly from 
the library functions.

cheers,
