Should I be stopping at the beginning and end of each piece and back stitch to secure these?
No ... there's no need to fret. As you add on the layers of blocks, the stitching will lock things on.
The only place I do a lock stitch (not a back stitch, is when I am doing the final borders. and there'll be no further layers added.
