Meat is obvious--you have to have BBQ chicken, you have to have pulled pork, you have to have ribs. Brisket is good too.
With all that meat it can be pretty heavy, and I know people love potato salad (I do too), but it can't be the only vegetable. Having fresh fruit gives you a refreshing and clean-tasting side. And it will hydrate you a bit, because let's be honest--you're going to be drunk out of your mind. Having a tray of veggies with dip isn't a bad choice, either.
Speaking of which, the alcohol: some sort of light beer is good; I like Abita because that's what I've been drinking for ages, but Newcastle is perfectly serviceable as well. You're probably going to have people who hate things that taste good, so bring out some IPAs for them. Anchor Steam? I don't know. People who like IPAs deserve whatever they get. Gin and tonic is a wonderful summer drink if you're looking for cocktails. Hard lemonade is a good idea, too. Soft lemonade for the kids. And water.
