hi simboy welcome to fs and to simviation! (I am sure you'll like it here....
these are the answers:
1) (I am not sure I have fully understood this question.... but I'll give it a try) You only see the heavies (the big planes) because you only go to main airports... try small airports like meigs or sde dov (in israel) and, trust me, you'll find plenty of small airplanes....
2) this airport in the pic is no other then the beautiful KLAX
3) on the ground... release your parking brakes (press "." or the trigger in your joystick push the throttle to about 20%-25% precent... and don't pass the 20 knots (with the heavies: 777, 747, 737, airbuses...)
4)unfortunately fs2002 doesn't have any pushback cars (unless you donload an addon or something.....) in order to push back press: shift+p, if you want to push back to a certain direction press: shift+p+(1 or 2, "1" in order to turn left and "2" in order to turn right).

Have a nice flight, and again welcome to simviation.
