The best tip when smoke is involved with food is "less is more better". Food safety aside, using excessive smoke is one of the most common errors that younger cooks experience. You want to expose your food to a light and delicate amount of smoke.
Beyond grilling, you will see some regional differences in terms or techniques when cooking with fire, heat and smoke. A catch all is term is 'barbecue', which (in my vocabulary) refers to cooking meats with indirect heat which has a light component of smoke involved.... "I'm going to barbecue some ribs, and a pork butt". However, I can substitute the word 'smoke' or 'smoking' and I could mean exactly the same thing. Or 'smoking' can refer to working with foods that have been cured.... things like bacon, ham, pastrami or even fish. Then there are a bunch of sub-categories like 'cold smoking', 'warm smoking', 'hot smoking' and even 'flavor smoking'. Experience will come at it's own pace, but you are in for some good experiences along the way.
