Congrats on the purchase! You will find that the unit requires little work once you set the temp. I use a remote thermometer just to watch the internal temp, which varies +/- 15 degrees or so from the set temp, ie the unit will heat over the set temp by 15 degrees or so, then cool down to below the set temp of about 15 degrees, before cycling back on to re-heat the unit. Everything that I have smoked has come out delicious!
I use cherry wood that appears to be very dry, so the first couple of times I was getting flare ups and heavy smoke within the first 30 minutes or so. So, I now soak the wood chunks and that has resolved the issue. You definitely don't need much wood to get a nice smoky flavor.
Good luck, and enjoy!
