As in the above posts, use SHIFT + P for a push back, then press it again to stop the push back (make sure your brakes are off). You can also do a power back if you want, just press F2 to engage the thrust reversers.
Air brakes are generally known as spoilers. They help decelerate the aircraft as it begins its descent for landing (could be for numerous reasons: slowing down to prevent overspeed, to aid in reaching 250 knots before crossing below 10,000 feet, to help descend quicker, etc.)
Generally, the spoiler lever will be on the left-hand side of the throttle quadrant. Use it only during approach and landing, and you should be good.

Use the / key (the one with the Question mark) to deploy the spoilers, and press Shift + / to arm the autospoilers, which will engage when you hit the ground.
Another thing, with the pushback, if you press Shift + P, followed by 1 or 2, it will turn the nose 90 degrees left or right, depending on the perspective. If you are looking from the front of the plane to the back, 1 will turn the tail right, and two will turn the tail left. Obviously, if you are sitting in the cockpit looking forward, 1 will turn the tail to the left (the easy way to remember is 1 is left of 2), and two will turn the tail right. If you don't want to go the whole 90 degrees, just press Shift P once to stop it, and press it again to keep moving straight. For example: if you wanted to turn the tail right (looking forward) 45 degrees, you would press Shift + P, followed by 2 (not the two on the number pad, but rather above the letter keys), until it gets to your desired angle, then press Shift P again to stop moving, then again immediately to start moving on the line you are on. If you do it quickly, you won't even stop moving.
