I alternate between Famous Dave's Rib Rub, which I found in the grocery, and "Bronzeville Rib Rub, which I found online at www.thespicehouse.com. Either way, I apply the rub and let the ribs sit overnight. Before I start the smoker, I take the ribs out of the fridge and let them come up to room temp. I mainly use mesquite chips for ribs. I've tried creating my own sauce, but after reading the labels on sauce bottles, I've settled on Stubbs brand regular barbecue sauce for just about everything.
This may be too simplistic for advanced BBQ-ers, but it works for me.
