I will answer as much as I can in your order.
1: Your oil light will always be on if the engine is not running and the key is on. It should go out within a couple of seconds after starting.

2: The oil light will not effect anything coil related, unless wires are somehow crossed somewhere. Normally totally independent.
When you swapped the wires, did the other coil stop working? The yellow wire had juice but not the blue wire? Is that right? If you disconnect the oil light, what happened?

So if you connect the yellow wire to either coil, that coil fires but not either coil when connected to the blue wire?

I just want to make sure I have it all.
