1965 I-6 won't start

I have taken over a 65' w/ an I-6 from my sister in law's father who has recently passed away. He was fixing it up for my niece so I have now taken over those duties. I have not played with the car at all, just seen it. It is in very good condition, but will not start.

I figured it would be one, or all of these things:

Battery, Distributor, Bad/old fuel, Carb.

So I thought I should bring some Stabil, carb cleaner, battery jumper, and a few gallons of new gas

What should if anything else do you think I would need? Also where should I start to diagnose the problem...other than the battery?

Thank you!

check the points .019 gap then check the coil to the dist

Thank you1
