^FYI the new movies will almost certainly not be based on the Timothy Zahn books you are referring to. I would be completely shocked if that turns out to be the case. In fact Lucas made it sound like he himself has written the outlines for 7-9.
Regarding your criticism of the prequel films:
They feel "made up around the original trilogy". This is purely intentional. It may not be evident upon first viewing the prequels. But each scene (damn near every plot point) is a mirror of another point in the saga. Every character's experiences are replicated by another character.
For instance, off the top of my head, in V, R2D2 is spat out of the swamp monster and at the same time the Millenium Falcon is spat out of an asteroid monster. Han and Leia fall in love on an asteroid, Luke and Leia are born on an asteroid. C3PO gets built just as Darth Vader is getting built (they are both nice and shiny at the end of III). R2D2 gets electrocuted twice -- the first time this happens, Luke gets his hand cut off, the second time it happens, Luke gets electrocuted. This sort of shit is mirrored throughout the saga and it makes each viewing a new experience. Check out the link above for a bunch more. It is seemingly endless.
And while some of this is likely unintended, most of the mirrors are crucial to the main point of the whole story: good can easily turn to evil, it has happened before and will happen again, and most important, it is happening now, in our world.
