OK after quite a bit of testing I figured out most of the issues I was having before. I managed to finally get the shield and sword into the game.
Yes the sword is in his side and the shield is only shielding the sun from him but this is progress lol.
It seems when you have diff versions of PyFFI and Blender NIF scripts you get diff results when doing this. I couldn't get the animations to work unless I used the force. When I reinstalled I took the version Deliverator was using(this took away those letters I was getting) but then I ran into more problems when loading different .nif's in blender(even civ4 vanilla units), i deleted the controller's using nifskope and that let me load them but without the Stage 1 info and my lack of knowledge I returned to the version I was using before.
Seeing how I was able to get the unit in the game before just lacking the shield/sword I looked to the tutorial part where you assign the vertex group, I wasn't using the material slider to set that up properly, seems that is the only way to go about it. Selecting the sword and the armatures going into pose mode and trying to parent the sword to BIP R Hand but that didn't work.
Now my two problems are when I join the meshs together and then assign them their vertex group it moves the sword/shield see above pic. the other problem is I am trying to assign the shield to a different material group (right now I have 2, 1 for the body and the other is for the shield and the sword.) right now both the sword and shield are assigned to the BIP R Hand vertex.
All in all though things are moving along great considering. I will play around with all this more. I'm thinking I might need to do all this before I join the sword and shield to the body but that still won't fix the flying shield and sword issue.
Again, thanks Deliverator for your help and guide.
Edit:




First thing i did was added materials, assigned 1 to sword other to sheild. Then joined them all. assigned vertex groups and moved/rotated the shield/swords 
This unit is also from the Total Realism mod. I figured I posted it enough around here people might wanna know. My thanks to them for making a nice looking highlander.
Deliverator how did you go about having the different shields/hair color in the same unit?
