Retexturing and Then Some

[redbrook]

I was interested in retexturing the Mercenary Grunt outfit - or at least I thought I was. I'd like to use it as a base and retexture some of the skin shown while wearing that outfit: the arms, hands, and neck area. I thought all the armors would be a full body replace and I could retexture the limbs and such from there. It seems I was wrong.

 

If anyone can help, I'm curious how I might go about adding the arms, hands, chest, and neck areas to the item and how I would go about adding texture to them. Going in to this I thought the G.E.C.K. would be a bit more transparent, like the Morrowind construction set. I have Blender set up to read .nif files and I have Photoshop set up to read .dds files. I'm quite new to all this, so if anyone has any advice or knows where I can find a tutorial that could help, I'd be much obliged.
