I would like to see the responses on this as well. 
I don't have a clue about what is 'proper', but I normally just tighten any one screw
unless it is something that I want to be sure that it doesn't come loose from the chuck.
I think #1 is ruled out because the scrolls aren't perfect and the individual jaws are going to get different amounts of pressure on them at different diameters. So in my thinking, going around the chuck and hitting ALL the screws is just added insurance.
I have more problems with drill chucks than I do with lathe chucks though. (That reminds me... I need to pull apart one of my Super-Chucks and check the jaws on it.)
