2 pc Diffuser & Grill Grates

Merry Christmas, Everyone!
Just received my 2 piece diffuser and Grill Grates for my YS 640 & have a few questions for the group.
1. If I'm only planning on smoking something should I take off the Grill Grates and replace them with the normal grates that came
with the smoker?
2. If I'm planning on smoking and then doing a reverse sear on a steak or roast should I remove the cover plate on the diffuser prior
searing?
3. Is there a preference when smoking to using the top or bottom shelves and if using the top shelf for a roast will putting a drip
pan to catch all of the juices interfere with the smoking process?
Thanks in advance for your responses. Gotta love having this smoker!
