1966 Dart troubleshooting

Man, what a great amount of information to work with thank you so much. So, I'm going to start checking things one by one, starting with distributor cap. Contacts obv don't look brand new, but I'm not sure if they are worn enough to warrant my attention. I uploaded these, could ya'll tell me what you think about them while I get working on the other stuff mentioned in this thread?

Here are the pics:
