When using someone's kamado (as I don't have my own yet) and for smoking in general i find large bits at the bottom of the charcoal is good for long cook. If I want a shorter period with more intense flavour smaller chips on top.
Let the kamado get close to your desired temperature within 10-15-20-25 degrees (as you prefer) and then start closing vents so it continues to rise slowly. If you have a pit thermometer, that will help you watch the trajectory and rate of increase. Small adjustments are best until you see it is quite a flat curve. Taking a slow approach to heating up means that as others have said you can heat soak the ceramic so you get the full radiative and convection effects. That's the whole point of the kamado!
With experience you will anticipate better where you need to be on the vents and which vents you need to focus on. Bottom is accelerator top is brake. Of course the quality and moisture on the charcoal will affect things.
Set alerts for plus or minus 5/10c to intervene once set up. Small changes due to thermal inertia.
Having said all that, don't worry about the precise detail either. Enjoy and taste. It's all about trial and error and trial and success.
My general tips are:
1) avoid temp overshoots due to thermal mass
2) monitor the temp trajectory with a sensor when you're starting out
3) react early with small adjustments
And yes, always use a basket - it means your charcoal is less spread for a direct cook, but it is more concentrated an much better airflow. ..and for indirect it's more controlled/even than resting coals on the clay.
You can actually (if you're using a basket) dispense with the lower grate IF you want more airflow and more heat for searing or pizza.
