He applied it by figuring out that some species died because they overpopulated and didn't have enough resources to sustain life.
Adaptive change is the province of natural selection and natural selection is one of the main drivers of evolution. Natural selection selects from the individuals variations in a population of organisms on, basically, reproductive success and this adaption is passed on to progeny which changes the allele frequency in the population which is evolution.
No. Natural selection requires reproductive variation to work on. Besides reproductive variation and natural selection, there are various forces, biochemical as well as population dynamical, that affect the allelic composition of a population.
Darwin developed The theory of evolution by natural selection.So, to answer you question, all of it!You need to make a distinction between evolution, the change in allele frequency over time in a population of organisms, and natural selection, the nonrandom survival and reproductive success of randomly varying organisms. Natural selection is the main driver of evolution.
Natural selection is a mechanism of adaptive change in evolution.
Non-random mating is otherwise known as sexual selection. Some see this as distinct from natural selection, but I think that sexual selection is merely a form of, or perhaps more a complication of natural selection. Selection, natural or sexual, is the effect that "guides" evolution, that allows evolution to produce populations suited to their environment.

it relies upon the population
Evolution, of course. Evolution can happen without natural selection in some cases; drift, flow. Generally though, natural selection causes evolution and then, by definition, would come first.
How it can change in response to its enviroment
No, natural selection is believed to result in evolution.
Stabilizing selection occurs when the extreme forms of some trait are selected against by natural selection. It is a force of natural selection which causes evolution (definition: change of allele frequency in a population divided by time).
Perhaps not, but evolution can exist without natural selection.
Natural selection is one of the 'guiding' principles of evolution.
Evolution by natural selection.

Natural selection directs evolution; it cannot stop or prevent it.
