First up...
Take a little time and go to the Training Arena (TA)
There is usually someone in there who will be dedicated to getting you up and running in a proficient manner.
There are several "easy mode" planes that are reasonably armed with gentle handling characteristics that are good planes to learn in.
One tip is to turn off the stall limiter as soon as you can, it does it's job well but it severely hampers your planes' turning performance.
For starters, I'd recommend the Hurricanes since they have gentle ground handling and give the beginner a good "feel" for the limits of the aircraft. I'd spend a bit of time in both the 1 and the 2-C, the 1 teaches good manoeuvring skills since you are actively encouraged to keep the aircraft pointed in the right direction because the engine will quit if you push negative G's. The Hurri 2-C has a good gun package and it will translate the skills you learn flying the 1 into kills to keep you encouraged.
Once you get some proficiency in these aircraft you can move on to the higher performance rides with some confidence.
Welcome to your new addiction.
