For library books, there is no way around using Sony Reader Library OR ADE. Even if you have Calibre and all the DRM-removal tools in place, you will still need Sony or ADE software to turn the acsm file (which is a reference to the actual file) into an epub file.
I am on a 2010 MBP running OS X, don't know what bit mode, and I can run the Sony software with no problems.
