Help For New Owner

Fist off, I don't like the fact that my 2nd post is a plea for help, but time is of the essence.
I just purchase a '64 Cuda 273 for my son's 16th Birthday on Dec 28th.
I'm looking for advice on what should be done to the engine to make the car as dependable as possible. The car idles really well, but hesitates upon throttle.
I've ordered new cap/rotor kit, new accel plug wires, new plugs, belts, hoses, filters etc.
The previous owner changed out the manifold and put on an edelbrock manifold and edelbrock 650 carb.
Should I change out the points ign system first?
If it where your car.... what would be the things you would do first?
Thanks for any help that the guru's can provide, and I look forward to both of us being active on the forum.
Regards,
Mike
