Historically, the way to organize things when you had such long communication delays was to give the forward commanders all the information possible as fast as possible and trust them to make the right decision, based on the intent of their original orders and their basic mission (in this case, to defend the Imperium).
There are also standing orders: if X happens, do Y. Of course, these standing orders can be far more complex and I'd imagine it'd be a major part of the planning staff's job to draft good standing orders taking into account the planned movement of other forces, training and repair schedules, etc.
In wartime, I imagine the Imperial Navy works with a "hands-off" approach to command; Sector Command mostly serves as an information conduit (getting intelligence to the tactical commanders) and a reinforcement/logistics center. Sector Command takes its orders from the Sector Admiral, who takes his orders from the Sector Duke and Domain Archduke.
Peacetime is different. I think that Sigg has the right idea for normal operations: the local Navy forces still have their general orders from Sector Command, but exactly how those orders are put into effect depends on a lot of things, including what the local noble wants. However, I don't think that a local Navy officer has to obey the local Noble, no matter how high a noble that is, but not listening to the noble will get the Navy officer in trouble, the trouble depending on just what the officer did do instead, and how much actual power that noble wields.
