As to your first question, it may currently be easier to use wb_command -cifti-separate to get the different hemispheres and voxels (either by structure or all in a single file) as separate GIFTI/NIFTI files. The GIFTI files made this way have direct correspondence to vertices in the relevant .surf.gii files.
