Why does Gauss's law apply to any shape of a closed surface?
If you are convinced by the sphere argument, then consider for any irregular surface a spherical surface within it that contains entirely your charge. …

Confusion about electron flow and current
Current doesn't refer to any specific direction, neither does it require the flow of electrons (any charge carrier will do). … If your current is generated by the flow of negative charges, we simply consider an equal and opposite flow of positive charge. …

Surface bound charge density in dielectric displacement
As for the point about the surface charge, Griffiths only derives the expression for a gaussian surface in the meat of the dielectric volume, where $\rho = \rho_{f} +\rho_{b}$ is obviously true (the surface … So we are evaluating this surface charge after all -- it is just hidden in the $\mathbf{P}$. …
