Dave, Yes, I use the bottom grate all the time. I can see your point about the water, but I usually don't see more than 10 or so degrees difference between the grates, so it doesn't bothere me much.
At home, most of my smoking/grilling is done on a BGE. But in competition, we use the WSMs exclusively, and I also use them for the odd party jobs. For a wedding we cooked for, I did 10 9-10 lb butts in the 22.5 WSM, 5 on each grate, and they were all done at just about the same time, and I used a clay saucer vs water. I started the cook at about 7:30 PM, topped off the lump at about 10:30 PM, let it settle, and went to sleep. Next morning at 8, was still cruising along at about 230 or so.
I don't think there really is one right way. The "right" way, is whatever works best for the person using it. So I wouldn't tell anyone they're wrong to use water, or sand, or a clay pot. If they're having trouble, I might suggest they try a different method to see if it helped them, but I wouldn't suggest someone was wrong for not doing something the same way as me.
As to "dialing in" the temps. What I normally do is start my coals minion, with top and bottom vents fully open. When the smoker temperature reaches about 190, I shot the bottom vents completely. With all 3 of my 18's and the 22, this works well. I usually settle in around 235-240, which works for me.
