The way to tune this is to set up three or four different PID loops, each of which are tuned to make the arm respond nicely when going to a specific place. Then, you can take your kP/kI values that work for each of the locations and find a nice curve that fits them and use that curve to modify the gains based on where your arm is.
apalrd posted the same idea earlier in the thread.
