A "College Survival Kit" does sound like a good idea. I think it'd be neat if you had a combo of handmade stuff in there as well as some of the more practical things. For the latter, she'll probably thank you when she's going shopping for stuff and gets to save a few bucks on some of the essentials!
For handmade stuff, since she loves reading, you could probably make her a few bookmarks. Or, if she's into a certain series of books you could make a related project. For Harry Potter, for instance, I've seen those knitted scarves and you could probably crochet one of the animals from the series. Since she loves music, you could probably make her a mix CD or burn some CDs of artists that you think she'd like. The coffee aspect is a bit tough, but you could probably make a cool math-related toy. I've seen people customize Rubik's cubes and even make their own from dice (math related because you can use algorithms to solve them :p), or maybe you can do something similar. I know I've seen some math-ish toys on here before!
For the practical stuff, I'd use this list: http://acatnamedollie.livejournal.com/391.html
It's got TONS of stuff on it, and I find it to be a great guide of everything you'd need to bring to college. You could maybe customize some of the stuff on there to make it more personalized.
I personally am graduating this year, too, and I know photographs will be a blessing for me. Perhaps some of her friends and family would be well appreciated.
