You should never put a stop marker at the end of your movie. It can cause bugginess. The DVD player will automatically return to the menu after the movie anyway.
But other than that, you're good to go!
For all intents and purposes your question has been answered.
The following is a just in case contribution to your thread....
From what you wrote, you targeted your question at what has to be completed with disc menu customization before clicking Done to that phase and moving on to burn to disc. Is that correct? Or, were you targeting in all that whether or not the Premiere Elements burn to disc is finalized after the burn to process? If the later is the case, you may be interested in my observations on that matter. If not, please disregard the following which goes into a lot of details on the matter of Premiere Elements disc finalization.
