Hello Nbednaz16...Jasper has given you good advice. It will take some experimenting/trial-and-error on your part to figure out how much wood and smoke to apply to your cooks. Everyone's tastes are different...some like heavy smoke flavor, while others like more subtle and mild smoke. The best advice is to get a hot bed of coals going first...you can do that by starting with charcoal, or by burning a few splits of wood until they burn down to hot coals. Then just add a chunk or split of wood to the coals as needed.
The biggest challenge with your rig will be temperature control...especially if its your first try. All offset smokers, even the high end ones, require some tending and some experience to really dial in the desired cooking temp range. If you haven't made any modifications to that Char Griller, they have a bit of a reputation for being less than air tight...and controlling airflow is the key to controlling temps. Many guys will seal up leaky seams with gaskets or with food-safe high temp caulk. The goal is to get your pit where the only places where air can enter and leave the smoker are through the dampers and vents. Then, with some experimenting with adjustments to the dampers, you'll soon have a good grasp on controlling your pit temps with air flow. Every pit is different, so it just takes some time and a few cooks to figure your's out.
One thing that might help, if you haven't already tried it, is to build a fire in it and run it empty for a few hours. This will allow you to play around with damper control...getting some idea of how well you can control the chamber temps without worrying about ruining an expensive slab of meat.
Hope that helps...good luck! And be sure to let us know how that first rack of ribs turns out!
