What HOTAS do you have? Start by carefully binding everything. Do this in the first training mission, against the canisters, so you can test&try anything. After that is done, head to the 2nd mission versus the Sidewinder. Do not shoot it. Just practice following it, and keep your crosshairs on it as much as you can. If you can consistently follow him from <1km, fight him. If you want to learn to fight with fixed weapons, do this mission frequently. If you are not going for fixed weapons, move to the 3rd mission (2v1) and repeat until it is easy. Make sure that you control all axis, thrusters, FA on/off, primary and alt fire, sub-system targeting, ship selection, chaff and SCB directly from the HOTAS. The rest can be added as you encounter a need for them (gears, panels, you name it).
Also, check out JoystickCurves. It allows you to customize the responsiveness at every position of every joystick and will make things a lot easier. Many people diminish the response when making small adjustments, so you can fly more accurately.
