Start looking now. I read how unhappy you are in the other thread. You can't stay in that situation for 6 more months, without trying something to change it. You'll be miserable. If management gets its act together soon, you can always stay. But you won't know if something better is out there unless you look.
I would deal with the vacation dilemma later. It may end not up being an issue. Worrying about it is a waste of energy at this point.
