Yes, the high temp and venting are one in the same. Basically, you want to get your grill to about 450°, stay there for about 30 mins, the 50° every 30 mins, until you start to get the paint smell. Once you get that, you can stop there, and let your grill cook the stuff off.
Brisket is a lo/slo, you seem to want to do beef. That's fine, but consistant temp is more critical with beef. If this is what you choose, get your kk to temp, stable, for an hour before putting the brisket on, you should be fine. Do you have a meat thermometer? Not totally necessary, but very nice to have. You want briskets to be in the 200° internal range, probe tender being the deciding factor. Probe tender is a sharp object going into your brisket like a hot knife into warm butter.
