You used numbers, so that's going to be the easiest way for me to respond:
1. Mine is still a hair off too, That's all fixable though.
2. I've gone back and forth on whether the gold bar has a gradient or whether it's just a trick of the lighting and shadows in the screenshots and image. I have the gradient as a correction layer over top of it, but have it turned off for the time being...it looks better without it.
3. Care to share your reference for that?
4. Still nowhere near done the journal. Color matching it will most likely become the bane of my existence in the coming days.
5. The author bar, like the gold bar, is something I've gone back and forth on. Looking at the screenshots, on the spine, it appears that it is the same color above and below the gold stripe, and on the other images, there is a noticeable purple hue in it (Even after I've color corrected it to properly set the white point and black point) so, based on my best information, I'm calling it purple, until I can find reference materials that say otherwise.
6. Thanks, amazingly it's all raster graphics. Since I know the ultimate print size of this thing, vectors would have slowed me down.
Where you heard that there wasn't any writing on the inside? Do you have a good source? I was under the impression, based on what was written in that other thread, namely, "The detail that is put into the jacket is amazing though with the depth that there is about the author and such," that there WAS content there. Since we don't see an "about the author" on the outside, it stands to reason that it was on one of the flaps.
Also, I believe there were multiple versions of the cover made. At least one without the picture of the author on the back, and another that continues the bottom, dark (Black or purple) bar onto the back of the book. So that further confuses what constitutes SA.
Also I'd love to see your progress! I always love to see how different people can interpret the same thing. It's amazing how two people can come up with different methods for the same thing.

EDIT: I should also note that what I posted is extremely low quality (To prevent people from just enlarging my image for their own purposes) so the colors are all a touch off...the gradients are much more pronounced, and the colorss much richer in the full-quality PSD.
