@Bruce Pearson - GO FOR IT!!! Ribs are one of the easiest BBQ cooks there is.
Up to you whether you remove the membrane on the back or not? Simple process - use a paring knife to pull up the membrane on the end bone, use a paper towel or dish cloth to grab the membrane and just pull and peel it off. It usually breaks so you'll have to do this a few times to get most of it off. Removing it helps get more seasoning into the meat. If you decide to leave the membrane on, don't bother putting rub or sauce on the backs, as it won't penetrate the meat through the membrane.
I slather plain yellow mustard on them, then a liberal dusting of whatever rub you like, just like a pork butt. I'm not a big sauce fan, so I normally don't sauce them, but on the rare occasion that I do, wait until they are almost done before putting the sauce on so it doesn't burn. 10 - 15 minutes with sauce is generally long enough to get some mild caramelization without burning the molasses/sugar/honey in the sauce.
Just to help out, here's a pic of the "bend test" on how you know that they are done, as they are too thin and narrow between the bones to reliably use a probe thermometer. When you see the meat pull back from the ends of the bones about 1/4", lift up the rack with a pair of tongs about a 1/3 from the end and let the weight of the rack bend the rack downward. If the meat starts to tear in the middle, they're done.
