With respect to a voltage regulator, such as shown here, I am confused about a few things:

1. If the power sources is a battery, with the output voltage from the regulator be constant, even as the power is discharged (and the input voltage drops)?
2. The do "waste" power, correct? In my case, I want a 6V output, but would like to use 8 (1.2V) batteries to make it last longer. Could I just use the regulator to get to 6V and still utilize the full power from the batteries (and not as wasted power...or with little wasted power)?
3. Conversely, can I also use a step up regulator, with a single 1.2V, to get to 6V? That would be handy if weight/size is important.
