From what I understand, air gets thinner the further up you go. This I assume is because Earth’s gravity pulls all the heaviest particles down to its centre. I’m wondering about gravity itself though, is there a gradual shift in the strength of gravity as there is in the consistency of the air, or does gravity apply to the whole field surrounding the Earth up to the very perimeter and then quickly fall off?

Earth’s gravity reduces the further up you go until it becomes insignificant, but it never falls to zero. So technically Earth’s gravity (or the gravity of the matter that Earth has formed from) is felt everywhere in the observable universe.
Air gets thicker closer to the Earth’s surface mostly because it’s being pushed down and compressed by the air above it (air, unlike water, is very compressible).
