Take off is actually quite easy. On your first lesson, it's likely you'll be doing the takeoff. Just point it straight, compensate for the left turning tendency, and gently pull back.
A friend of mine was given as a gift one of those "Discovery Flights" where you are taken up and get to fly the plane, which is supposed to entice you into signing up for lessons.
Not only did he get to do the takeoff, they let him do the landing.
He had a little trouble keeping it from turning on the takeoff, and a lot of trouble with that on the landing. Afterwards, they found out why. Something had punctured a tire before takeoff, and it was a little flat during takeoff, and a lot flat during landing.
Took off and landed on my very first time as well :-)
(San Diego, Montgomery Field, March 2011).
The explanation my instructor gave me for the landing were perfect: Line up to the runway like this. Lower throttle and add flaps at these intervals. At the last checkpoint, point the nose of the plane at the numbers on the runway, like you were trying to collide with them, except that at the last moment you pull up and cut power to idle.
Worked like a charm. Maneuvering on the runway is harder than flying and landing. ($$@#!#$%! pedals working 2 ways and in the opposite direction from what I expected :-) )
Landing is a different story...
