Stab trim position indicator.  This scale tells the pilots where the stab trim is currently positioned.  The green band indicates the safe trim range for take-off.

Speedbrake handle.  This handle deploys the speedbrakes on the aircraft.  The speedbrakes deploy by "splitting" the upper portion of the wing flap up, thus creating more drag to slow the aircraft down on landings, or whenever there is a need to slow the aircraft down in flight.  The forwardmost position is "off", one notch to the rear is "Armed" and then there are more rearward steps for each amount of speedbrake deployment needed.

Parking Brake.  This is a small metal lever that is pulled upwards to lock the brakes.  You shove the toe brakes (on the rudder pedals) as far down as they will go and then lift the lever.  The red light will illuminate to indicate the parking brakes are active.  To release them, you just depress the toe brakes again and the lever will automatically drop.

Throttles & Thrust Reversers.  These three handles (marked 1 - Auto Throttle, 2, 3 - Auto Throttle) are a dual function mechanism.  The long handles extending forward control the thrust reversers and they have three positions.  Retracted, Armed and Extended.  To arm the thrust reverser, you bring the handle back until it's nearly vertical.  To extend the reverser, you bring the handle rearward.  They will not move into the extended position unless the throttle arm is in the Idle position.  When the reverser extends, a 2 peice metal clamshell device pops away from the rear of each affected engine and closes around the rear of the engine, directing the engine thrust a bit forward and avove and below the center line of the engine.  This is used to slow the aircraft down during the initial moments of touchdown.  If the pilots were to stand on the brakes without using the thrust reversers first, the brakes would quickly heat up and catch fire.

On the #1 and #3 throttle arms are the "Go Around" switches.  When the aircraft is in an autopilot controlled descent to landing, pressing either one of these switches will command the autopilot to increase the thrust by automatically moving the throttles forward and it will also command some up elevator.

Fuel cocks.  Right below the throttles are the Fuel Cocks.  These three levers control whether or not each of the three engines gets any fuel.  In this image, they're in the down or "Cutoff" position.  They would need to be moved into the open or "Idle" position to allow the engines to be started.

Stab Cruise Trim.  Just to the right of the fuel cocks is the Stab Cruise Trim switch.  This switch is used to adjust the horizontal stabilzer trim while the aircraft is in flight.  The reason it's there is because it moves the trim tabs at a MUCH slower rate than the yoke mounted switches do and allows the pilot a finer degree of control than could be achieved using the yoke mounted trim switches.  To the right of the switch is an orange lamp.  This is illuminated whenever the trim system is activated.

To the right of the Stab Cruise Trim switch is a pair of metal levers that affect the trim system in some way, but I don't recall their exact function.  If anyone can provide insight on these, I'd appriciated it. *g*

Douglas Snow informs me that:
"As for the stab trim paddle switches - they are the power switches to the powered trim system.  Move them to CUTOUT and the manual wheels come into play."

Flap Lever.  This controls how far the leading and trailing edge flaps are deployed.  Each position has a notch that requires the lever to be moved in a "U" shaped pattern.  This prevents accidental deployment of the flaps as well as accidental changes in degree of deployment.
