Re: 430EX question

If you do use E-TTL with slave flash units, then units placed in group C (now assuming the older, optical system) are handled as background illuminators.

Flashes in group A and B are assumed to illuminate the main subject. These two groups share that task. You can set the ratio of the light A:B, as well as the overall strength of the combined groups (FEC). Then groups C has a separate FEC control.

There's nothing wrong with using the flashes in manual mode. You probably get a more repeatable result that way. But since you seem to be really overwhelmed by the power setup procedure, perhaps you should try the E-TTL approach first, and then at least take some of the manual process out of the equation.

As said above; You shoot digital. Take photos, look at them, adjust and try again. After a couple of hundred shots, you'll see the pattern.
