Various tweaks and updates

This is a pretty big update, adding a lot of new information, reorganizing some, closing some issues, and even a few minor little things. I'll keep pushing to this branch, as it is a WIP pull request. But it's less work for me to do it all in one big pull request and it's probably the only way I will get this done :)
