Finite-volume method for compressible laminar N-S flowsolver

I successfully implemented a code to solve the supersonic laminar flow over flat plate as described in the book by Anderson,Jr (Chapter 10). This used MacCormack scheme which is a Finite-difference method.
I now plan to solve the same problem using a Finite-volume method. I understand that it is conventional to apply upwind methods for inviscid terms and central differencing schemes for the viscous terms for numerical simulation of compressible viscous flows. So, my doubts are:
1) Can I use a first-order Local Lax Friedrichs (LLF) for the inviscid fluxes and central differencing for the viscous fluxes? Or should I use a second-order LLF scheme for the inviscid fluxes?
2) The timestep (CFL condition) specified in Anderson book is for MacCormack scheme. Can I use the same timestep for my Finite-volume method?
If anyone has already written a code for solving the supersonic laminar flow over flat plate using any FINITE-VOLUME technique, can you please mail it to me. I will be thankful as this is a good study problem (Blasius flow) and will help me understand the workings of a Finite-volume based flowsolver.
