Practice vertical turns, i.e. loops. When you can loop well you can fly anything else you need. All the standard aerobatic maneuvers are good practice for aircraft control but dogfights are mostly vertical turns.
Air combat is maneuvering but it's not maneuvers so much as it's pursuit curves. Use lag pursuit to get behind the bandit and lead pursuit to close the distance and/or take the shot.
The barrel roll, a loop and roll together, is a common result in air combat, learn to minimize your forward travel in practice. In a dogfight you'll see barrel rolls in a rolling scissors, fly the maneuver with lead/lag pursuit in relation to the bandit.
