These are all questions that are not particular to deal.II, and so this mailing list isn't quite the right forum to ask these questions. In any case, I would recommend you take a look at the literature on solving the Navier-Stokes equations and see what people recommend in this area. One starting point would be the book by Stefan Turek, for example.
