So I intend to do armor conversions for the UNPB body I've downloaded Blender version 2.68.a and Nifscope what else do I need to get up and running? And for the record I am a complete utter noob with these programs so any tips or vids that help explain would be most helpful.

This http://www.gamesas.com/topic/1343653-creation-kit-video-tutorials-merged/ has many helpful links for you.

Modding is very addictive. The learning process, and the chance to create content in your favourite game is a thrill. Most modders usually spend more time creating mods than playing the actual game itself .

Yeah I looked at some the ones I clicked which looked relevant were dead watched a few youtube vids with blender and now my brain is going to melt down, the most learning I've had in a long while.

This. Wave bye bye to playing for a while. Once you jump down the rabbit hole its difficult to get out

I believe I can now begin to import a body mesh but I'll do that or try to after some downtime to cool my brain.
