For the smoothed/non-orthogonal normals/tangents I think re-orthogonising them in the fragment shader should work.

I've seen some suggest doing so in the vertex shader too, but either way I'm skeptical about the correctness. I suppose it depends on what the authors of the models and normal maps expect to see (but then you have the problem of stretching in animation, in which case in may not be possible to visually check all possible states).

I did this for my animated character, reorthogonalizing in vertex shader, and renormalizing in fragment shader. as long as the mesh do not become degenerate it works quite fine.
