If you're sure the motor is an 82, then it probably didn't come with points if it's a U.S. model. As inxs said, check under the left and right chrome covers above the spark plugs. If there is pretty much nothing under them, then you don't have points.
I'm going to assume you are pretty new to motorcycle mechanics with the following explanation, so forgive me if I made an incorrect assumption. Here’s a very simplified explanation
You have a motor and carbs and spark plugs. You need the coil that gives the power to make the spark plugs actually spark. You also need something to tell the coil when to fire. This is where the points/igniter box/boyer ignition/pamco ignition you are hearing about come into play. To tell the coils when to fire, you need a way to determine where the motor is in its cycle. This is either done using the cam or the crank. You also need a way to advance the spark as the rpm increase. This can be done mechanically or electronically. All of the different systems you are hearing about use a combination of these to provide the signal to tell the coil to fire at the proper time.
Points (72-79) use the cam for the engine position, and a mechanical advance.
TCI (transistor controlled ignition, 80-83 models, also called the black box or igniter box) use a pick up on the alternator (crank) to get the position of the motor and use the black box to figure out the advance.
Boyer ignitions use the cam for the pick up signal and use an electronic box to digitally advance the spark
Pamco ignitions use the cam for the pick up signal and use the stock advance.
So assuming you don’t have points, you need a coil, and one of the above ignitions systems, a voltage regulator/rectifier, and a battery (unless you plan on doing a permanent magnet alternator conversion). That will get your motor running. Whether you use a starter or not will play into what battery/alternator setup you end up using but I wouldn’t worry about that or wiring it all up just yet. Look through some of the
simplified wiring diagrams that inxs posted and just focus on the ignition stuff for now.
