A little help with a model

[Vartoz]

Hi folks, i`ve been trying to make a modification on an armor but after reading 30 pages on blender tutorials still got nothing.

As you can see in the image:

I´m adding a coat to the antagonizer´s suit wich i had to modify in the chest area to avoid clipping issues.

I also changed the arms for the chinese stealth armor arms but modify the texture to make it look like it´s all part of the same armor.

And Finally, i modify the helmet, removing those goofy antennas and modifying the visor, adding googles to the helmet (not really necessary but it looked better)

But in order to add this to the game i have to either do this in Blender instead of using Maya.

The thing is, i already reed like 50 pages of a blender tutorial and still have no clue how to remove the arms or modify the UVs, not even mention how to keep the rigging once i`m done with the modification.

Is there a specific tutorial that could help me? Please don`t bump this thread, if you think there is no other tutorial just say so, otherwise, i still have a lot to read.
