Hello Mike ! It is a bit unusual panel. The A/P button, HDG knob and V/S knob are at the center area of throttle panel.
There is also a PDF Operating Manual in the aircraft's folder, you can get more info from there
The left heading is the gyro drift effect. You should feel it at every single-engine propeller aircraft. The torque of the propeller makes a counter torque on the aircraft body which makes it bend left or steer left on ground. On twin engine planes therefore the propellers rotating to opposite directions... but not in FS. They somehow forgot it... If it disturb you too much, you can eliminate it at the Realism settings: turn off gyro drift.
