The standard works of the LDS church are on-line at www.lds.org. It would take a lot of reading of those works to put together what I wrote. The book "Mormon Doctrine" by the now-dead Apostle Bruce R. McConkie has a lot of information, but also includes some of his own opinions, not accepted by the rest of the church leadership. The Encyclopedia of Mormonism probably is better at representing current Mormon doctrine, but I haven't read it yet.
