I think everything your asking has been answered somewhere in this forum before but anyway your numbers sound right for a early 352 engine, I don't think you can tell for sure if you have the 352 or 332 form the outside of the motor you need to take out a spark plug and measure the stroke.
The colors for the 352 would be Blue for the block, Black for the valve covers & white for the air cleaner and fan (non AC car).
I have found that the Ford blue tractor paint that Tractor Supply sells is a close match, most the Ford blue you see in the stores matches the 1966 and up blue which would be incorrect for 1958
