The problem with trying to use a finished dimension piece of material for a two sided project is it's very hard (as you've found out) to find exact center and then depend on the material to be cut exactly square.
My suggestion would be to make your material 8"x8", add a 7"x7" vector to represent the finished project size. Next put a 1/8" circle vector in the scrap material on the horizontal center line. Use the Mirror Select Object to copy the circle to the opposite side of the material. Make sure to check Flip about job center and Create a mirror copy.
For the two registration circles I'd use the Drill toolpath and a 1/8" EM, set the depth to material thickness plus 1/8". Create another Profile toolpath using the 7"x7" vector to cut out the material to final dimension.
Change Flip direction to horizontal.
Cut the two registration circles first then the rest of Top side. Flip the material and use 1/8" pins in the registration holes to align the material, run the toolpaths for the bottom side with the "cutout" profile toolpath last. Depending on how you're holding down your material you may want to use tabs for the "cutout" profile.
How this makes since....
