I live in SC. So here goes:

1) Use a homemade BBQ sauce. Avoid store-bought pre-made BBQ sauces like it's cancerous.
2) Slaw. If you use mayo, you MUST use DUKE'S. Otherwise it won't taste right. If you use a hint of mustard, use French's.
3) Do not EVER put the slaw on the sandwich, or on top of the meat.
4) If you're making BBQ sandwiches, the only thing that goes in the sandwich is: Meat (pulled pork) AND sauce. Nothing else. Anything else comes as a side.
5) NEVER chop the meat. It has to be hand pulled. Trust me, your guests will definitely know if you chopped it.

[On that note, they like to put peppers and onions on BBQ in Delaware... Too much Italian influence I'd say!]

Edit:

While cooking and eating, Natty Light, Busch Light are acceptable. Additionally, the music de-rigueur is Skynnyrd. Just pop a Skynnyrd CD (or in the 8-track if you're old school) in there and let'er rip. Forget about Bob Seger or any other Yankah'.
