What kind of fog levels do you imagine one might expect to find on 3 year old Vision 2 film if it's been frozen during most of that period? How 'bout any other potential problems one might incur?

I would hope that the fog levels had not risen by more than 0.05, I would not use the stock if the fog levels had increased by 0.10. This assumes that you know what the fog level was when the film was put into storage. The Kodak website gives average characteristic curves for all their stocks. You could get an estimate of the rough values for fresh stock from them. Vision 2 200T stock has fog levels around R:0.15, G: 0.45 and B:0.95.

You could experience problems if the cans had been opened before freezing and sealed up in high humidity. If the film is unopened it would have been sealed at the Kodak factory at the correct humidity. You must remember to allow the film to warm up before opening otherwise you will get condensation on the film.

SHould be minimal. 500 will have fogged the most, as it is most susceptable to background radiation. 50D the least. I'd say that even with 500T it'd still be good, just overrate it a tad to compensate.
