You don't need to bend anymore in the real tight curve where the fibers are starting to tear. But,I still urge you to bend the binding where it does not perfectly fit the form. You can use the wood,with the form inside it,just as you have it in the picture above. Press the bending iron against the outside of the binding where it does not lie perfectly against the form. You can see a gap just before the peak of the "horn" there. I would not recommend you just trying to pull it down with tape. Sooner or later,the binding will open up the seam there again. The maple will continue to pull at the glue for the rest of the life of the instrument if it doesn't fit. The glue,sooner or later,will lose the struggle.
You can definitely over bend the waist of the body. There is no tearing there,and it will really help the binding to not separate there in the future.
You can just dampen the wood and run it against the iron naked. Be sure to not get the iron hot enough to scorch the wood. You'll end up with a very noticeable thin spot in the binding by the time you sand the scorch out.
