I know I will probably get booed for this one, but if you want to make some really easy, fast BBQ sandwichs...take a brisket, put it in a "throw away" aluminum pan, and pour your favorite BBQ sauce over it (I like "Sweet Baby Rays"). Then put it on your Weber using indirect heat for a couple of hours. I comes out very tender. Slice it up, and serve on some nice rolls.
Yes, I know this not smoking, or grilling, but it tastes great and is easy, and if you want to feed a bunch of people it works quite well. I used to do this for lunches at work when I was an electrician. I would start the charcoal at about 9:30am, put the meat on at 10:00 am, slice it up at noon, and everybody chowed down!!
