Boundary conditions for hyperbolic problems, especially for hyperbolic systems are tricky and quite different to e.g. elliptic PDEs. If you want to read up on this, I would read up...

1.) I wonder if we should relate this to making scalar nodal functions (e.g. pressure), and one could be to compute the maximum wave speeds. In general, I prefer to...

It would be maybe a good idea (for future) to make a new equation system out of it...maybe compressible Euler equations directly formulated in density, momentum and potential temperature instead...
