Controlling placement and movement of scripted MC's

ok this is the whole thing i’m trying to do

i need to have movie clips created at certain intervals. i do not understand how to set, call or clear intervals yet.

a MC is created via scripting. it is positioned in the middle of the movie using exact x and y positions. after 2 seconds, that first mc(mc_1) moves to another position and a second empty mc(mc_2) is created under it, loading a different image, and then moves to it’s position of exact x and y position.
after 2 seconds a third mc(mc_3) is created and moves from under mc_2 to it’s exactly x and y position.
after 2 seconds a fourth mc(mc_4) is created and moves from under mc_3’s position to it’s own exact x and y positions

it sits like this for 8 seconds. after 8 seconds, mc_1 and mc_2 both move off stage to the right. then load in different images and move back to their original x and y positions from the left of the stage.

2 seconds passes and mc_3 and mc_4 both move off stage to the right. then load in different images and move back to their original x and y positions from the left of the stage.

8 seconds after this occurs, mc_1 and mc_2 do their thing all over again loading in yet another image set…etc ad naseum.

does that make sense? i know it’s a lot of help to ask for but i’m totally stuck.

this is the scripting that i have so far

createEmptyMovieClip("mc_1", 10);
mc_1._x = 22
mc_1._y = 5
mc_1.loadMovie("Jewelry/hughes.jpg")

createEmptyMovieClip("mc_2", 9);
mc_2._x = 202
mc_2._y = 5
mc_2.loadMovie("Jewelry/Large-Coral-Ring-w-leaf-pat.jpg")

createEmptyMovieClip("mc_3", 8);
mc_3._x = 22
mc_3._y = 185
mc_3.loadMovie("Jewelry/Kitty-Catapillar.jpg")

createEmptyMovieClip("mc_4", 7);
mc_4._x = 202
mc_4._y = 185
mc_4.loadMovie("Jewelry/Opal-&-Diamond-Pendant.jpg")

many thanks
