I was wondering if anyone had any dimensions or design criteria on the appropriate position for chain idlers on a front wheel drive system for a bicycle.

Yes, the bigger the better. Some very fast bikes use aluminum or even plastic. While durable, I don't know anyone who uses steel.

Also it should be a steel sprocket as large as practical.

I think the main concern is steering feedback when you are pedaling. The side of the chain that is under tension should be as parallel as possible with the steering axis to minimize the moment.
