I can't comment on the American Holly as far as deer-resistance, I've never planted it here in upstate NY (zone 5) and have seen it very rarely (always in a VERY protected spot). But I wouldn't classify the standard hollies used around here (Meserveae, which includes the "Blue Girls/Princesses'/Maids" and male counterparts) as truly deer-resistant. They attack mine every year if not protected.
As far as hardiness, though, I can say that if you wait a few years I'm sure the hardiness zones will be adjusted, thanks to Global Warming. I figure I'll be zone 6 in 5 years if current weather changes continue. I'll have to start boning up on new species.
