Might once have been true, but no longer. Google "aeronautical" and "SiRFStar III". Convergence.

Moving has an effect on the position of the satellites relative to you and complicates the locking calculations, resulting in longer lock times.
Theoretically true, but the effect is not very significant with modern GPS chipsets, and hard to separate from the effect of being inside a metal box (car or plane).
