I could refute everyone of your examples.
But, I'll just do Leia. It is implied that she's speaking of her birth mother all these years. But, she could also be talking about her adopted mother. And since she is a child of the Chosen One, the "images and feelings" she has in her memory could be of Padme....because of the Force.
Now, because you're an Original Trilogy fan, you'll dismiss my logic as a "stretch." But, if you call that a stretch, you'd have to call the logic of a lightsaber a stretch as well. Both are in the realm of possiblity within the Star Wars universe.
And because I'm in a good mood, I'll do the Jedi Force issue.
It's quite easy if you think about it. Qui-Gon was the first to discover the path and he only shared this peace of information with Yoda who learned and passed it to Obi-Wan. It is implied, in Episode II and confirmed at the end of the Episode III. No other Jedi know of this discovery, hence the many death corpses in the Prequels. Again, not out of the realm of possibility in the Star Wars logic universe...
