Jessica, I've done both for different reasons. I think I would keep listed only what you have made up and ready to ship. I would deactivate the others, and then relist them when you get back and are ready to roll again. I would take the ready to ship ones with me plus enough of the packing materials, and ship them once they are sold. That way you won't need to spend time making new bandanas, but will also be able to take advantage of the holiday sales.
One more thing, plan to close your shop early for the holidays so you have time for your own holiday shopping and preparations. You will need a breather. In fact, if I were you I would not keep my shop open after the first week in Dec. and then reopen it after the first of the year or when you are rested and ready. Your new job is the most important thing right now, so focus on that. Also be sure to leave time for you to do all of the things you and your family normally do for the holidays.
Congratulations and good luck.
Oh, be sure to put a note at the top of your front page (I would do it in caps so it stands out more) that you are away but will be filling orders and answering messages, it just might take a little longer than usual.
