ignition coil questions

I'm running the mopar electronic ignition, i'm using a standard ignition module a borg warner select coil with an echlin cap and rotor and borg warner supermag plug wires. I'm just wanting to know what the best set up would be to get more juice to the plugs? i need to learn this ballast resistor and coil thing too, because i was thinking about getting the mallory canister coil with mallory pro side winder spark plug wires, mallory also sells a ballast resistor that i guess i coul get, but its 15 bucks and i can get a borg warner or echlin ballast for around 5 bucks.
But i do want to have my coil and ballast set up correct so i am not frying 1 or the other.
