It is my opinion that the verses you listed cannot be answered without an understanding of who God is and what He's trying to accomplish. It is also my premise that if we don't undertand what the overall message of the Bible is and what God is trying to communicate through it that the Bible as a whole will make little sense.
Many religions lift passages out of the Bible and use them to come up with their own distorted view of who God is. There's been an immeasurable amount of anguish and harm caused by those who have twisted God's word in this way, creating manmade religions that have little to do with God's true nature. Using a warped view of the Bible as a basis for discussion will never lead to an understanding of who God is and will cause many to reject God.
However, I do believe that if we can find what the central message of the Bible is that nearly all of it will make sense. I compare this belief to the workings of the wheels on a covered wagon. Everything revolves around the hub. If the hub is weak, then the whole wheel will eventually fall apart and the wagon won't function. But if the hub is sound, then the rest can fall in place.
I don't believe your questions are the "hub of the wheel". Furthermore, I don't think they can be answered rationally without knowing what the "hub of the wheel" is.
I believe the "hub" of the Bible is found in Genesis 1-3. These chapters describe a perfect world, one that God created and then called "good". God created a perfect man, a perfect women, a perfect human relationship, and a perfect place to live in.
What's more, chapter 3 indicates that God walked in the garden with the ones whom he created. I interpret this to be a literal physical reality. God not only intended for us to have perfect lives and a perfect world, he also wanted a perfect, personal, and intimate
relationship with us.
The lives of those first two people were complete. They were emotionally, physically, and spiritually fulfilled. God intended for them to live eternally in this perfect state.
The interesting thing is that the first 3 chapters of Genesis closely parallel the last 3 chapters of Revelation. These passages are near mirror images of each other. For example, Revelation 21 describes the perfect world once again, one where there is no death, no sorrow, and no tears. It also describes a world where God once again literally dwells among men.
And so, though your questions are important, I think the more crucial questions are these:
1. What happened to the perfect world described in Genesis 2 and 3?
2. Is today's world what God intended it to be, or is the world in the first 3 chapters and the last 3 chapters of the Bible more representative of God's intent?
3. If today's world is not what God intended it to be, what if anything has God done about it?
I would be curious to see your answers to these questions. But I may not be able to respond to your posts for a few days due to other commitments.
Note that this discussion could be continued in another thread if that seems more appropriate to do so and if someone wants to get it rolling. But I don't mind continuing it here, and I do think it ties into some of the original discussion.
