First thing first, i have no idea how to use Blender. So i need a good tut for a total new user. Second, do i need NIFscope?

I recommend you Noob to Pro tutorial for Blender and you need Nifskope to set the textures for the object ... and maybe the animations

you can also ask for advice i am sure people would be glad to help you with whatever mods your working on

After you're a bit more comfortable with Blender (or not. It does tell you what you need to know), you might take a look at Blender/Custom Cuirass. I tried it and failed...

lol the best advise ever

was that Sarcasm i detected there Jaysus?

Shepard

it is nifskope not Nifscope
and if you want make new armor cloth you need nifskope
download here Blender 2.46, Python 2.5.2, Blender NIF Scripts 2.3.3, NifSkope 1.0.10, PyFFI 0.10.9 http://www.tesnexus.com/downloads/file.php?id=12248

also here http://wiki.blender.org/index.php/Main_Page search the Tutorials in Main page

I'd use Blender 2.48 (currently beta). It does work with NIF scripts 2.3.9 and it has some very nice features for the armor/clothing modeler (shrinkwrap in particular).

As the writer of the custom cuirass tutorial above, which many people seem to have trouble following (possibly because they haven't seen the updated version on the Modeling and Texturing WIki), I'm generally available to give help one-on-one via PM or email.
