1. Think of the planets not on a plane, but sitting atop a bucket with an elastic fabric placed over the top. If you put a billiard ball in the center, the shape of the fabric would actually be curved around the sun conically (but in all directions). If you tried to roll a marble from one side of the fabric covered bucket with the "sun" in it, the marble wouldn't roll straight across, but start circling around the "sun" in in increasingly smaller spirals. This is a good model for the orbits.
The curvature happens because the shape of space with mass is always curved - not planar.
In those early days 5 billion years ago, particles started condensing as they bounced off of each other (slowing, gravitationally pulling together), slowly flattening around in the accretion disk because of the laws of angular momentum. In short, the (mostly) planar shape of the orbits is the result of the massive gravity of the sun and those early particles bouncing off of one another.
Of interest, Pluto is off that plane quite a bit.
2. I think I understand what you are saying here, Donkeyman, is that you are inclined to theorize that the current universe could at some point coalesce back into a singularity (Big Crunch) to such a point that spacetime once again starts anew (Big Bounce). So, so many questions, aren't there!
One of them being how dark matter and energy would play into such a cycle of events - when we don't even know what it is. And then consider the weirdness of the universe in which atoms hadn't formed, nuclei hadn't formed and density was much greater than black holes, but still didn't collapse back on itself! And how could "something" start out with infinite density holding all of space and time? The answer is that it probably didn't. We just don't know.
It's humbling to consider that most of what is out there, we cannot yet perceive.
3. Yes, most of critical changes, including an offset that allowed the universe to form the way it did, after an extremely small fraction of a second in which space and time formed as we like to measure it. Yes, it's still evolving - faster - like raisins in a bread dough that is rising in different directions all at once, while the raisins pretty much stay the same.
