I would like to be able to monitor the supply voltage and CPU temperature from software. Does such a thing exist and is the Raspi Model B board equipped with the necessary hardware to do this?

For the supply voltage AFAIK you'll have to add an A/D. That's what I do for my weather balloon tracker. In that I monitor the battery voltage but it could very easily be changed to modify the 5V rail or whatever.
