Since you are focusing on the forward(plane closest to the camera) it would be natural to have the rear most area less in focus.
Using the tripod allows using Live View and manual focus but another way is to recreate a flag, a focus target placed on the top surface that aligned with the centermost plane you you seek. Anything that is a good focus target with contrast would work, a match box for example stood on the top to use as a focus target, on the desired FP. When focused, remove the matchbox and shoot. That way the front and rear depth of field will be balanced on either forward or backwards from that target. This should either be in VF manual or LV. You can also AF by half pressing the shutter to start focus and then press the AE/AF L button to lock that focus and exposure and shoot.
F22 is too small an aperture to prevent diffusion with the 16mpx of the D7000 so that should be opened up a little. Use the lowest ISO you can get the exposure since you are on tripod and in manual exposure mode.
What lighting source are you using outside of the light box? Continuous? If you lower the power of one of the light or move it slightly further away, subject detail can be increased. Edges are not well defined now because there are not enough shadows. Edge detail is low because the subject is of such a limited color and edges are soft. The lightbox is used to remove shadows from small objects that have a great deal of fine detail(along with other uses). In this case you actually need to emphasis edges more. Instead of a softbox, I probably would have used a multiple flash configuration to define edges more.
