Keep your vents wide open if grilling burgers or steaks. Probably only a single layer of coals too (or just slightly more)... I had a hard time getting a high temp using mine with coals stacked up to the grate (I'm a Smokey Joe newbie too...got one to use a few months back while my BGE was experiencing "technical difficulties"...

). But I've read that a single layer of coals is the appropriate setup for the Smokey Joe...I'm thinking that there wasn't enough air space for air flow with how I had mine set up. I would say that about 1/4 to 1/3 of a chimney of charcoal would suit you just fine.
Also, if you're grilling up chuck roasts as steaks, I would suggest slicing them thinly and against the grain. That cut can be tough if you're grilling it like a steak...They do pack a lot of flavor though. I'm actually putting a chuckie in the crock pot tomorrow for pot roast...it's a great cut for smoked pulled beef and pot roast!
