New YS1500 owner in NE OH

After putting up with various big box store smokers, I've finally taken the plunge and purchased a real smoker. While I wait for the new unit to be delivered, I have a couple of questions.
First, are there any guidelines for meat placement in the smoker? I've seen posts where people say they do the large cuts (brisket/ butts) on the bottom grate and all others on the top rack. Is this the general consensus, or are there other considerations? I can see doing this when cooking multiple meats like in a comp, but if you are just doing some ribs is this still the case? Also, if you have to increase the controller temperature to get the necessary grate level temp on the top rack, why wouldn't you just use a lower setting on the controller and use the bottom rack?
Second, if you open the sliding door on the YS1500 HMP to increase the temp on the left side of the smoker, wouldn't this increase in heat directly from the burn pot cause the thermocouple which is located right above the opening to think the smoker is getting too hot, and the controller would slow the feed of pellets, effectively causing the rest of the smoker to get cooler?
