One tip on any ride that uses lockers- you might want to bring a washable marker and write on your hand your locker number each time you get one. I have forgotten my number before and it was not fun to have to ask one of the attendants to open up every.single.locker. until I found mine. If you're not big on writing on skin, you can keep a slip of paper in your pocket.
Another note on lockers- the Hulk lockers are very small. A normal sized backpack may not fit. I had a little canvas backpack that wasn't very full and I had to shove it in there.
Sounds like you've got some good tips! One other thing is not to be intimidated by the wait time for Forbidden Journey, because the queue is just as amazing as the ride. 30-45 minutes actually gives you a great amount of time to absorb the details and get some photos, especially your first couple of times riding it.
