There's no way one single man is going to be able to stay on top of all that. He's gonna have to delegate authority. In the Imperium, with it's feudal chain of command, the immediate delegates are the counts, with each count or viscount ruling over a county of 3-6 worlds.
It can be rather interesting to take a subsector or two (the usual campaign area) and map the Counties based on the Counts and Viscounts set out by Traveller Map, then do the same for the Marquisates (usually no more than a pair of worlds). In many cases, you'll find a "leftover" population of Barons who answer only to the Duke(s) since they fall outside of the Counties and Marquisates. The Imperial politics of the region practically write themselves at that point, particularly when a colony and its controller end up in different Counties...
