For the kimono block -- Since you have a completed block you should be able to measure the width of the dark bands. Add half an inch for seam allowances and sew to a strip WOF (width of fabric) to the floral. I haven't figured out the yardage, but I think a 4-4.5" (or 5" and sew bands to both sides) will give you plenty to work with, with little waste.
