I begin with modding since a month so i am not expert.
If someone with more experience can give advice, so go ahead.
Basicaly.
Associate shape and sprite.(it is already in your case)

You need associate shape into frame of sprite. look the shapeid(5)(red arrow).
If your frame don't correspond, so click to edit (blue arrow).
click on the number of characterid to modify the number(black circle).
If characterid dont appear check if your FlagHasCharacter is set to true(yellow).
Associate sprite/frame

associate the frame(Tanga in the picture) with your sprite (red arrow).
sprite/class
In your SymbolClass associate the sprite with id (blue arrow).
name your class ( yellow and black arrow).
In your class.

In your class modify the frame1() with the modtype you want(red circle).
The class need a function with her name like the picture.
Associate your Modpackage with your frame.
declare a variable with the name of your object in your frame as a MovieClip (like the yellow)
If it's nameless, name it and if the " name : String=" don't appears check if your flagHasName is set to true;
Call it in ModPackage

Save you SWF.
Voila, you can use It.
Note for other modders: I don't succed to create a functionnal new class .
