Of course you have a transition period - I don't see why you find that odd. After all, people have those kind of discussions, where some people find different thing morally acceptable - today. Plus, you are placing the bounds on morality too wide - we can see that even monkeys have some primitive morality, so our non-ensouled, human-like ancestors would have more than that.
No, there aren't. You do have a bunch of distortions and outright lies by creationists, which you can see in the hoax filled videos you mentioned, and those are evidence of how low the creationists who made those videos will go to deny reality.
Which is why they are often older than the Bible? Along with the many records of the civilizations existing straight through the flood as if it didn't happen? And the other piles of evidence that make a global flood obviously mythical?
Here are just a few:

Sure you do. Simply provide a verse showing where Cain's wife came from, without making up things that aren't in scripture or ignoring the order of the text.
Theistic evolution requires no more significant an interpretation than you already use. For one example out of many, simply look to the fact that you think we live on a globe, despite the fact that a literal reading of scripture repeatedly shows a flat earth, under a hard dome. The scriptural interpretation needed to get to a spherical earth going around the sun is much farther from a literal interpretation than anything theistic evolution suggests.
Right. We can get guidance from God's other revelation - His creation itself, which shows through many different dating methods, all of which confirm each other (and are based on different phenomena) that the earth is much, much older than 6,000 years.
Like your other ideas, this is an interesting possibility. The DNA evidence do show a moderate bottleneck around 70,000 years ago, perhaps from the Toba explosion (
Population Bottlenecks and Volcanic Winter). DNA makes major bottlenecks datable, and is yet another reason the Noah's ark story is not literally true - because a bottleneck of 8 people, just a few thousand years ago, would be obvious (and is not seen).
