The answers to these questions are:
3. Focus circuit on one muscle group
3a. This should be the same muscle group as the main lift
You might've already considered this, but I thought I'd point it out just incase. If you spread the workload out over more muscle groups, your body will have to work harder to pump blood from one muscle group to the next, and then back again. So hitting multiple muscle groups in one circuit would give you a better workout in terms of endurance training. Not trying to be like "ur doin' it wrong", just givin' some food for thought.
