Help With NifScope and Relocating A Cape

[SpecterFan]

I am working on a copy of Ink's Storm_JimLee mesh. I need the cape to be 1\2 to 3\4 its original size. I shortened the cape using the Mesh Editor. Now the cape needs to be relocated and\or reattached via nifscope

How do I  do this? What needs to be done?

When I check my work with the Character Tool her hair does not remain attached; it floats. What do I do?
