My pictures are of no real use - they cover only some specific situations. And it's full of german script, since i wrote the instructions directly on the picture.... I put a proper NifScope tutorial on my to-do list.
(You are a modder as well, i am sure you know, how our to do lists look like
)
In the meantime...
There are already some good tutorials on NifScope.
Might be not enought for a Model-Rookie, but i think for someone who already knows what he's doing and only need to be pointed to where the right tools are, is should be good...
General Notes:
1) Many (if not all) useful functions in NifScope can be accessed from right Click Context Menu - just right click on a object to see what possibilites you have.
You can for example bring up the dialog for moving a object by RightClick->Transform->Edit
2) Almost everything is editable - you can doublecklick on any Values/References in the Block Detail window to bring up a input, where you can enter new data - like for example texture references.
There are 2 Tutorials from C.Roland that introduce what i concider to be the principal technique (applied to LH's and Units). You can do a lot of things, by just changing references, like it is done in this "mesh-switch". You can re-reference - as shown in the Tut - entire meshes, textures, properties, extra effects and even animation controllers and skin instances this way (Tho touching the later will usually cause a mess).

Note: You can also paste objects directly where you want them to be - say attaching a extra prop tp a bone - right click the Block where you want your Object attached, and use Paste Branch there, to directly attach the new thingie to where you want it to be.

Note: On some units nifsope will refuse to open up the UV Editor. This is because - depending on shaders - some units do not have a Base map. You can attach a base map, open the UV Editor, then remove the Base map once you are done. (The Base map is also the one you actually see in the UV Editor.)
