I think you should look at the specifications for the noise-rejection capability of those three-terminal regulators. They are simple and inexpensive but not particularly good at noise rejection. Some of the noise from the switcher supply will pass through. Is it enough to cause a real problem? Unknown to me as yet.
I think the linear regulator is mainly to handle low frequency damping where as for higher frequencies capacitors and inductors is helpful.
They do not exclude themselves, but they may be a cheap and fairly effective in combination.
