Answer 1

Actually your command should consist quotes. It will look like this:
app.executeCommand(app.findMenuCommandId("Toggle Transparency Grid"));
But I`ve tried, and it doesn`t do what you need, because it launches Adobe Anywhere.
Solution for second question is:
var path = "C:/Program Files/Adobe/Adobe After Effects CC/Support Files/";
var cmd;
cmd = "";
if($.os.indexOf("Win") != -1){
cmd = "explorer " + String(path);
}else{
cmd += (("open \"" + String(path)) + "\"");          // change var path for Mac
try {
system.callSystem(cmd);
}catch (e){
alert(e);
