It only adresses #2 insofar as it talks about baryon acoustic oscillations. They contribute to the CMB power spectrum, but in the end they are only useful as a measuring stick to calculate the Hubble constant. This theory does not explain the dark matter component seen in the power fluctuations at all. It also doesn't adress #3 at all (there are very concrete examples of lensing that any such theory would have to be able to explain).
