As far as the queue, I thought they kept everything in there until the first part of 2010? Once it finally closed is when they started actually re-doing the inside of the queue.
That's how I remember it too. And yes, it's high time that they repaint those coasters...their color schemes don't really match the theming of Harry Potter and the colors have faded to a silly pastel on both of them. Same goes with Knott's Berry Farm's Xcelerator: The track is now freaking PINK, because they've never painted it since it was new! They repainted the supports a year ago or so, but they left the track pink and faded...which looks ridiculous.
