As for games not showing as installed, it is possible for the library file to become corrupted. The game data is still there. Steam has just lost track of it. You should be able to tell Steam to install the game to the existing location and it ought to recognize the previously existing game files and skip downloading things that are already downloaded.
The issues you describe with games becoming uninstalled usually happens when Steam is shut down improperly. It's not guaranteed to happen every time Steam shuts down improperly, but it seems to be the commonly understood cause when it does occur.
