I don't think you really need to reload the same file. At the game that I'm building, I have a function called initVars() where I have all the values and positions set. When I want to restart the game, I simply call it. But if you want to reload again, the best thing to do is go to a new file "gameover.lua" or something like that and go back to your game file from there.

Now talking about your code, take a look at the exemple on how to use the main.lua file.

I have on my game a pause() function where I remove all the listeners and stop transitions and timers. When I want to go back to the game, the same function recreates all of this with the state that they were. To store the state, I have a few variables just for it.

One more thing, never forget to insert your graphics into the localGroups or they will remains at the screen.

Thanks for the tips, are there any resources/samples to implement initVars() ?

I can't send you my code because is part of my game, but try something like this:
