Sounds like you're approaching it realistically, nothing wrong with a down and dirty High School driveway rebuild.
As far as the bearings go, pictures can be deceiving, so only you can tell for sure if you're comfortable reusing them. I'd at least plastigauge them to make sure your clearances are acceptable if you reuse them.
With cleaning the block, knock the core plugs out, soak the block with oven cleaner, and spend your swear jar full of quarters at the car wash pressure washing it within an inch of it's life. Spend extra time blowing out all the cooling passages. Even new, these things had all kinds of leftover foundry sand, rust and crap in there, and the intervening 36 years probably haven't helped. You'll be shocked how much filth you flush out of there.
Once you've got it nice and squeaky clean, remove any ridge and run a dingleball hone through the cylinders, and slap some nice plain old iron rings on the pistons and send it.
Are the heads you've got 302s? If the valves and seats don't look too bad, lap them in and put 'em on with some thin head gaskets. I think 2.02s would be overkill for the stock cam.
Add a second hand intake, stock iron or something like a Performer or Stealth would be plenty good with a carb in the 600 cfm range.
If you're going to spend money on anything, spend it on the ignition. Sixty year old worn out distributors, as well as $50 Ebay whiz bang distributors aren't where it's at. Get something decent, or a nice rebuilt factory dist. (ala @halifaxhops ) to make sure you've got solid fire in the hole all the time, every time.
JMO, and good luck!
