I agree, sounds like you have a well thought-out plan, poetic. It sounds like you have the right kind of space, a defined target market and plenty of a market there without much competition. You may already know, but I'd look into the demographics of the students - is it a big area for artists or more the sciences? And if there's any way to do a little market research to see what college students in similar areas spend their money on, that might be helpful.
Do you have any room for a stage to incorporate the artist's playing their own music, doing poetry readings, etc? Many of the coffee bars I know of that are open into the night and have events also have a beer/wine license. Guess you'd have to determine what the costs and liabilities are in your state and if that would be worth it.
Sounds like a great idea, and I agree too, that it takes more than a love of coffee to run a successful business. Keep us updated!
