thought i'd get one last bbq in before the end of the summer. should be around 20 adults and a few kids so i'm wondering what to prepare. i'll grill a few home made burgers and some chicken kebabs and for the smoker i've got 3 racks of ribs, some home made keilbasa, a lump of belly pork or a shoulder and some armadillo eggs. this will be the first full smoke where other people will be eating the results so i'm after some advice on how to make it all run smoothly.

cooking order, biggest in first i suppose? pork joint followed by ribs, sausages and then the pork mince balls in last.
i've got a twin charcoal grill, is it worth keeping one on a low-ish fire with a large roasting tin and lid on the rack to keep things warm?
sides and sauces?
cheers all.
