Read here for the most part. But I will sum it up for you. You need a distributor, intake, carb, some type of ignition, fuel pump, and a fuel tank sump.
Distributor-You really don't want a points set up. At least go with the old Duraspark ignition. It really is easy to wire up. MSD is recommended though. Just make sure it has a steel gear on it. An 85GT dist. works good. You need to figure out your ignition preference and then choose a distributor to match. BTW, you can decide to go the duraspark route and still add the MSD later without changing distributors.
The fuel tank sump you will need to either buy one from like Granetelli (I think they offer one) or make your own. Again it is easier than it sounds. I used the stock pickup, using a piece of brake line in place of the fuel pump. Been going two years on that now. It is best to upgrade the fuel lines from the tank to carb but not necessary for the swap. You can hook the tank back up like normal providing you modify the stock pickup as I did. Then you will have to cut off the end of the line where you disconnected it in the engine compartment. Yes there are two. One is a return line which you won't use. Cut the stock fitting off and attach a piece of 3/8" gas line to there and run it to your fuel pump of choice and then from there to the carb, of course.
The fuel pump you can get a cheap ass $30 electric pump from autozone and wire it to a regular toggle switch or into your ignition switch. Or you can get a good holley pump about $100. Either way they need to be closer to the tank than the motor. Which is why I say just run all new gas line. But, you can pickup from the stock location (by the sway bar) and mount it on the fender somewhere and then run line to the carb. I wouldn't recommend it but it does work.
Sorry so long, but this is basically what you need to know. The link above goes into more detail.
