I can only respond to your first question...

It has been some time since I worked with the NOX Tensor based solver  
and even longer since working with TENSOLVE package in FORTRAN.  I  
think some convergence parameters can be set the same, but others are  
not compatible because the two packages employ fundamentally different  
algorithms.  One is a large-scale iterative solve (inexact), the other  
is a direct solver.  If you provide more specific information about  
parameters you are interested in, then I might be able to help further.

Best regards,
Brett Bader
