If you poke around at Touregypt, you'll see that these questions have been addressed.
Concerning your layers question, the AE's only leveled their work every tenth or so layer of stone. I'd guess that near the top they didn't pause to level the layers as often, so the layers you see are thicker.
Also, the stones in the upper two-thirds of the G.P. are decidedly smaller than those further down, and they get even smaller the higher you go.
The layers of stone, however, vary in thickness.

I couldn't find anything related to this on a search of touregypt.
I've also lost my bookmark of the variations in pyramid layers. I thought it was in Petrie's
work but apparently not. I'll grant you that the most wedged shaped layers fell at somewhat
regular intervals but then so do the thick layers.
It could mean that these wedges were to compensate for accululated errors but even were
this shown to be the case, the question would still remain how so much error would accumulate.
Most of these errors would cancel each other out from one layer to the next if the only factor
causing it were poor cutting or poor measuring.
In other words we're still left to wonder how a structure built to such tight standards would have
such sloppy work in these thicknesses. Sure they wouldn't show and didn't matter, but surely it
would have been far easier to maintain true lines if each layer were the same thickness from
side to side.
