I have two archives in .blend format (Imp | OpenGameArt.org and http://opengameart.org/content/troll-mauler) But I have two problems, the first and the IMP file does not convert to .FBX always an error message, the second problem is that the Troll file I can not apply the textures already removed the texture of the .blend file and created a material but only applies a blur on the character, then my question would be how to get to the imp file be converted into .fbx with textures if possible and how to make me able to use the textures of the troll file. Another doubt would be, if it is possible to apply the character animations in the third person in the IMP file.
Which error?

Anything else is possible too what you have asked for, but nothing is so easy to answer.

I would suggest you to start with own basic meshes and test export pipeline.
