These two sites have great information and links to other sites, I may try to start cross referencing to update my accuracy. I was using the LDS Church News site as my main source, but these two are great sites!
I love the data and maps at http://ldschurchgrowth.blogspot.com/ - I'm now following it's blog
The temple pictures and updates are great at http://www.ldschurchtemples.com/
Of course the church has a fantastic map at http://lds.org/maps/
and a wonderful old site has been refreshed http://cumorah.com/
