In this case the construction of a proper Jacobian is VERY important for the 
solution speed.
Given my experience, it is much easier and effective to first write the 
linearized system of differential equations
and then to discretize it than to  first discretize the nonlinear system and 
then linearize the resulting algebraic problem.
Note that the two approaches do not always produce the same Jacobian.
