How should I properly understand Full Preterism and its implications over the creation story and millennial kingdom?

This is a two part question. 1. In Full Preterism we localize all meaning of the "cosmos", "world", & "heaven and earth" to mean nothing more than "covenant". Apocalyptic language used in the Olivet discourse and revelation are not about the end of the world, but actually the end of the Jewish age. Therefore we are in perfection now. There are no plans to redeem the world, only to redeem a localized group of people. Judgment is the same, There is only judgment for a small localized group (Jews in 70ad). This hermeneutic is largely based on Jeremiah 4:22-26 where the world is described as lifeless, void, without form, and there being no sun, as the author describes the destruction of the first temple. This language clearly mirrors that of the creation story. So, to consistently apply the hermeneutic we must acknowledge that Genesis 1 is not about creation, but rather, the story of God stumbling upon a world, and creating covenant with Adam. Further, we need to localize the judgment of the flood. Judgments (as we know from 70ad) are not actually over the whole world, but only a small, select group of people. 2. In understanding revelation 19-21 there is a vital piece of text that states Satan will join the beast and false prophet (Revelation 20:10 And the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown). So this has a large implication over the 1000 years. The 1000 years is likely not literal, but during the 1000 years Satan is bound, until the brief time that he is loosed. Then he finally he joins the beast and the false prophet after the 1000 years. This creates a struggle, because Satan cannot join the beast and the false prophet, until the end of the 1000 years, where he was bound, and then loosed for a short time.
