Bastid, I would agree with MushCreek. Maybe 8 - 10 lbs of charcoal and only a 12-15 lit placed in the middle of the unlit. Make SURE you catch the temps short on the way up like Harbormaster mentioned. Also, if you leave the lid off for any length of time, you will have a major temp spike that may take hours to get back down. Good luck bro and keep us posted!!
Edit: Bastid, I actually start my drums 55-60 minutes early to make sure the temps are stable. 200 degrees on the side thermometer should be around 225-235 at the center of the grate.
