Autotakeoff should be on by default.
When you press fly, if you advance your throttle all the way (shift = I believe) and touch nothing, your plane should take off, raise it's gear, and begin climbing on auto-trim for speed. Once you get up to about 5,000 feet or so and have some room to maneuver, then you can disengage the auto-trim for speed by moving your controls. Have fun.

Oh, and there is more to do than just fly planes. If you do not have a joystick yet, you can always drive a PT boat, man a fleet or ground gun, or drive an amphibious vehicle, tank, or AA vehicle. Lots to do besides fly, and much of those things can be done pretty well with a mouse and the keyboard if that's what you have.
