Clinton's team tried to hand Bush reports of terrorist dangers and plans to deal with them. Bush's team (including Rice) wouldn't hear of it.
I don't know why they didn't want to talk about terrorism or do anything about it. But in such a situation it would have been Rice's job to measure the real relative dangers of things and bring the important ones to her boss's attention. Rice seems to have the done reverse, ignoring issues her boss didn't want to deal with.
As for truth and lies, I don't see a lot of shade of grey here. Rice outright lied about having been warned about terrorism before 9/11.
