I have read over all of the posts that have gotten here thus far. I too have a daughter in college out of town (LSU/Baton Rouge). I have provided her and her BF with BoB's.
They have pretty much the same gear that you have provided. I hadn't thought about a roll of quarters (which I carry in my BoB) but I will take care of that TODAY, since they are here in town. There are many vending machines around towns/cities and many of them may still be working when a snack or a cold drink would be most welcome. Many soda vending machines now carry bottled water so they could easily supplement their supply.
I think the laminated card with instructions on it is perfect for a young, inexperienced person who might find themselves in a deep doo-doo situation for the first time without Mom or Dad next to them.
