Making a choreographed group is pretty simple

If you press the choreograph button in the clothroom a grouping editor will open. In it you can select polygons (add and remove). This is the part of the cloth which will be manipulated (choreographed).

In the frame of your end pose of your figure you need to move the polygons to the place you want to have them there. You do this by moving and rotating the entire cloth so that those polygons are at the right place. It does not matter where the rest of the polygons in the cloth are. They will simulate as normal.

Be SURE to have the frame selected at which the end pose is.

Now run the simulation and see what happens

And have a look at http://my.smithmicro.com/tutorials/1420.html . It is probably better at explaining this
