Yippee I just figured it out!

myDoc = app.activeDocument
myOriginalStyle = app.activeDocument.characterStyles.item("[None]");
myFinalStyle = app.activeDocument.paragraphStyles.item("Paragraph Style 2");
myCstyle = myDoc.characterStyles.itemByName("Side");
app.findPreferences = app.changePreferences = null;
app.findPreferences.appliedCharacterStyle = myCstyle;
myFinds = myDoc.search("", false, false, undefined, {appliedCharacterStyle:myCstyle} );
for (var j = myFinds.length - 1; j >= 0; j--) {
myTF = myFinds[j].insertionPoints[-1].addAnchor();
// theText.move(LocationOptions.atEnd, myTF.parentStory);
myAnchStory = myTF.parentStory;
  myFinds[j].move(LocationOptions.atEnd, myAnchStory);
  myAnchStory.texts[0].applyStyle( myOriginalStyle );
  myAnchStory.texts[0].applyStyle( myFinalStyle,true );
  myAnchStory.recompose()
}
app.findPreferences = app.changePreferences = null;
 myFinds2 = myDoc.search("^a", false, false, undefined, );
 for (var i = myFinds2.length - 1; i >= 0; i--) {
 myLocation = myFinds2[i].paragraphs[0].words[3];
 myFinds2[i].move(LocationOptions.atEnd, myLocation)
 }
