Absolutely correct.
Some places not listed may have been hit, some not hit, some hit with either conventional weapons, sabotage, or both.
At the end of the day it's all down to the GM to decide just how screwed a place is. The books provide us with a framework to build on and as long as we're faithful to that framework and the intentions of the writers, the rest can be whatever the GM wants.

As for Langley, I don't know if it would warrant a nuke, I don't know enough about it and what's to be found there. However, it'd certainly be considered as a target by the Soviets for attack at some point. Perhaps it was a secondary or tertiary target only to be targeted in a full scale nuclear war, perhaps it was simply missed in the initial exchange. Perhaps it's already flattened. It really doesn't matter all that much in the grand scheme, only if a GM decides there's enough there to warrant the PCs checking it out for some reason.

We also don't know for sure that TF-34 docked at the Naval base itself, only that Norfolk attracted nukes totalling around 1MT, and 50,000 American troops evacuated from Europe with the Norfolk region as their main destination. Some ships may not have reached Norfolk, or been diverted to other Milgov enclaves along the coast. This seems likely given the logistical nightmare feeding so many people would entail.

Norfolk appears to have received an airburst(s) as ground bursts appear to be specifically noted in the target lists. Therefore radiation levels may be almost tolerable (look at Warsaw for example) and physical damage to infrastructure out of the immediate blast area is potentially repairable given time and resources. The warheads may have drifted off target by a mile or so as well, which would help to spare some of the necessary facilities to receive TF-34.

There also appears to be other dock facilities in the area besides the naval base which may have been pressed into use.
