I think you could go at Late Antiquity from any number of directions.
At my alma mater, for example, the Center for Late Ancient Studies is made up of professors from Classics, Religion, Art History, and Philosophy.
If your application is strong enough, the MA program at Memphis might make an excellent safety. It's extremely strong in Southern history.
Duke, WUSTL and UNC are also great choices for Southern history. There's quite a lot of work in gender studies at all three.
I've never been a big fan of rankings, since they're pretty useless for selecting graduate programs. A student looking to do Bronze Age archaeology would be best served at Cincinnati, for example, which otherwise has a good but not great program.
That said, I don't think anyone would dispute that Berkeley, Brown, Michigan, UT Austin, UCLA, and UNC are pretty solidly in the top 10 and are strong in most areas.
Carolina has a history track within their Classics program. I simply can't recommend that department enough. There is also a concentration in ancient history in the History department, but that leans toward the Greek side of things.

Penn and Chicago also might be of interest for ancient history.

You seem to be operating under the assumption that Classics is more marketable, which is absolutely untrue. The job market is horrendous.

Job prospects for high school Latin are better but still less than great.
umamei, you might want to look into Indo-European Studies at UCLA. It requires a couple years of Latin, but otherwise you'd be perfectly qualified. They have THE biggest names in the field (Calvert Watkins, Craig Melchert, and others), and it's still a new and developing program. It seems like it would be right up your alley.

The Classical Journal website has some pretty useful information about admissions expectations for various programs.

I would suggest something else...have you considered studying abroad? A semester or year abroad would give you the opportunity to pick up more Latin and possibly Greek as well, in addition to being an awesome experience. Failing that, I would consult the instructor of Latin at your college and see if you could take upper-level Latin courses as independent studies.
I would also recommend looking into a field school, if you don't have archaeology experience. I particularly recommend a dig in Cyprus I participated in, as it's completely free for participants (including airfare!) and gives a good background in Byzantine art/archaeology.

Don't forget to pick up French and German somewhere along the way!
Duke senior here. I wish I could have several more years here, so I'm definitely jealous of you guys!
I wouldn't rule out Chapel Hill, even without a car. The Robertson bus provides great transportation between Durham/Chapel Hill, although I have to admit that it isn't that great on the weekends.

The Chapel Hill bus system is free, so it's very easy to get around town.
Yes, almost definitely. I've walked to places in Carrboro from the UNC campus before, so it could quite possibly even be within walking distance, depending on where you choose to live.
