You started just fine, but the leap from myFolderContents to myDocument leaves out a few steps. You need to open each document and process it. So you need a loop:

for (var j = 0; myFolderContents.length > j; j++) {
var myDocument = app.open(myFolderContents[j]);
// the rest of your code goes here
}

Now, the only problem you might run into is if the opening of any of these documents throws up a fonts or links issue. Up to you whether you want that to happen or not. If not, you need to manage the interaction level. I'd do this:

for (var j = 0; myFolderContents.length > j; j++) {
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.neverInteract;
var myDocument = app.open(myFolderContents[j]);
app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
// the rest of your code goes here
}

I know this looks a bit inefficient, but my sense is that you should have neverInteract active for as short a time as possible.
