Yes, definitely take a read at netaces.org. The fact that you played "Air Warrior" or one of its kind will be beneficial, too.
One thing I used to do when I wanted to learn about the game was to "Fly the Plane That Shot Me Down Last". It keeps things interesting for awhile and will help you develop a good idea of what plane is capable of doing what in a given situation.
Or, you can fly the same plane for awhile until you get comfortable in it. Don't assume that the most popular planes (Spitfire IX, N1K2, P-51D, LA-7) will be the right ones for you. For me, the P-51D is a challenge to get kills in and I've had horrible luck in the LA-7 (though they seem to be able to kill me with ease). On the other hand, its easy for me to get kills in the 109G10, Yak 9U, Spitfire V, and Hurricane IIc. Its just a matter of finding a couple of planes you like and learn them well.
You'll find that the speedier planes such as the LA-7, P-51D, 190D9, and 109G10 will allow you to escape from a bad situation though you may find it harder to line up a target long enough to get off a good shot. On the other hand, the Spitfire V and IX and the N1K2 can turn with just about any plane through its maneuvers, but it'll be harder for you to extricate yourself when you end up on the wrong side of the fight - you'll have to finish what you start and hope you're the last plane flying.
My suggestion is, for your next flight, start with a Spitfire IX with the 2x cannons and 2x .50cals gun option. Set up your stick so that you can fire one set of guns or the other or both (which means you'll want a stick with at least 3 buttons). Get used to the different ballistics of the weapons. You'll find that the .50cals and hispano cannons are the better weapons out there, so you can focus on learning the flight model(s) of the airplane(s) and the various game components, like setting up your viewing angles and such. Then, try the Spitfire V. It'll be slower and its 4x .303s aren't as potent as the Spit IX's 2x .50cals, but it'll give you a good contrast in speed and turning of the two planes. The Seafire II (available on land as well as carriers) is similar to the Spit V.
That'll get you started.
