Just to clarify: there won't be a map download, the map will be available at some point for us to come back on it and have a look at the past... Nostalgia nostalgia

I guess there could be a way of copying builds to creative if you want to save them, but that would probably fall into the usual WE edit, which means it would cost diamonds. We can't start copying and saving all the individual builds people want to keep, or we would be submerged under demands...
For the second question, it is always safer to take out items you want to save before a WE. Items in frames and chest *may* disappear in the process, so if you want to be safe, just save them elsewhere.
Regarding bookshelves: everything is lost when moving a bookshelf. Books are saved with the coordinates of the bookshelf, which means that /everything/ will be lost for these. Please save them before!
