Eight suggestions on how 'BSG' could have ended better

I've already seen one person's conclusion as to how "Battlestar Gallactica's" creators flubbed the two-hour series finale and I tend to agree with a lot of this person's comments.
But my approach to this subject will be slightly different in that I will make recommendations on what could have made the difference in ending what could have been one of television's greatest drama series.
Instead, the ending left me slightly less impressed with the series than I had been over the course of the previous five years of its existence. It still, on the whole, was a well-thought-out, well-acted, vast improvement over the original 1970s series. But the ending, at least in this stage in looking back on it, left way too many loose ends. Yes, life doesn't leave us with neatly-tied packages; sometimes it takes years to clean up what one person leaves behind.
But this is a television show, and its creators and writers appeared to just throw their hands up and say "I quit" with the series-ender.
The thing which is the most difficult for me to swallow is that the crescendo toward which many character and story lines appeared headed just seemed to get forgotten about or abandoned as the end neared.
Genuine character resolution - following a character to his or her logical, at least plausible, conclusion - simply appeared lacking.
I read somewhere that the creators focused on the characters in the end, not the story line. Both are equally important, and one - the story - was largely lacking at the end.
OK, here's my list of what the shows creators could have done differently to make "Battlestar's" ending a fitting conclusion to the rest of the series:
1. Help Kara Thrace make sense. Kara just sort of "poofs" at the end; literally. She's there one minute and not the next. She's too integral a character to just disappear. Her death and later existence as a resurrected being is not fully explained; she even wonders aloud who she is. She deserves an answer and so do we.
2. Give "All Along the Watchtower" stronger meaning. It's a timeless song, there's no doubt, but its impact seems pervasive and guiding - it clicked on four dormant Cylons; Kara knew it as a kid; even human-Cylon hybrid Hera knew it and it helped get the colonists to Earth. There must have been a reason beyond what the creators have explained as it just being something which comes out of the ether and provides guidance. Its influence suggests someone else was helping it get that way. Who was that?
3. Let Gaius Baltar's heroism not be a surprise. He makes a major stand toward the end, one which seemed uncharacteristic for him. Just help us see how he went from the sniveling little brat he was most of the series to this stand-up guy. And he and Six turn out to be glorified narrators as well as types of Adam and Eve. Explain that better, please.
4. Help us understand who Daniel was. Was Daniel, the 13th humanoid Cylon, Kara's father? What was his role?
5. Who created the Final Five? In one episode, Ellen tells Cavil that he is named John, after her father. There's no answer to this question whatsoever.
6. Who is God? The Cylons are mono-theistic. The humans are not - they're polytheistic. How did it get this way and why do the two cultures make the distinction?
7. Let the final battle with Cavil's Cylons be less anti-climatic. Why couldn't we have some well-aimed gunfire in the ventilation shaft or a black-ops plan that worked or a Cylon model who turns on Cavil and blows up the base ship? The writer whose link I post above mentions how Cavil just sort of gives up in the firefight in the command center and eats a bullet. Not how his character should have ended.
8. Tell us how the humanoid Cylons and the humans co-exist on the new Earth. Do they just make babies and be happy with each other? Do they make babies with the Earthlings who are there already? Or are we to believe the mantra that it has happened before, it will happen again? At the very end, I think we're supposed to think that but I'm not sure.
Sure, I agree that consumers of television shows, books, movies, music, etc., should draw their own conclusions and not every last detail should be spoon fed and excruciatingly explained.
But these are just the eight things which come immediately to mind which would have made the series-finale so much more tangible and interesting.
