This is what I have for NAS Norfolk. The entries in bold are the ones that I've actually monitored. Hope this helps.
I have most of these, just haven't confirmed them in several years. But the big missing part is the HSC squadrons. I do know that 347.800 is no HSC-26 base; it was replaced by 346.275 sometime around 2016 or so. Here's what I have, with years reported for each freq:
