Upgrade Ignition help???

If I buy a street fire 6A type and coil from MSD what changes do I have to make to the wiring? And do I have to use a different distributor, I have a stock magnetic type? Does this bypass the ballast, what does the bassist do that I can,t get rid of it? Trying to get a better idea here, thanks for anyone that wants to take the time to help me out with this.
