What's involved in running a coffee shop?

OK, so. I’m 16. I have life ahead of me. My state has it set up so that the government pays for you to get as much college as you want under your belt during 11th and 12th grades. I’ll be doing that soon. While it isn’t necessary, it’s generally a good idea to have an idea of where you’re going so you know how to get there. In other words, I’m trying to figure out what to do with my life. The idea that’s really clicking for me right now is to open a coffee shop a small town. I love small towns, coffee shops, cooking, and, especially, forming relationships with people. What I don’t like about this idea is the business side of it. I’ve heard it said in the past that if you find a job you love, you’ll never work a day in your life. If I was going to have to handle the business side of this venture, I’d find something else, because this would not be that “job I love”. But I’m not even sure I have the right impression of what running a coffee shop includes. So I have some questions. I will appreciate any answers I get here. Thanks!
So my questions are:
-What would this venture involve? I’m thinking both start-up and day-to-day.
-Is my impression of the business side exaggerated? Underestimated?
-Would the management of such a business include enough work with money for me to think about a business partner? It just dawned on me today that I could have a business partner to handle money, while I handle the food, advertising, decorations, and day-to-day work.
-If I did have a business partner, would I still need business training? This is one of the things that makes me not like the whole idea. I don’t want to have to take business classes in college, if possible. Would a AS (or is it AA?) be enough? That’s a two year degree, btw. Or would I need a BS/BA? I could have an AS in business by the time I graduate from high school. That’d be alright, I guess, if I needed to.
-Thinking about start-up in particular, what kind of certifications and inspections are involved?
-Thinking about the day-to-day workings of the shop, what kind of liabilities would be involved? Specifically, would there be any problems if I were mainly catering to teens/kids? My mom thinks I would come up against a lot of liabilities if I were to have minors in the shop without their families. I’m hoping to set up this shop in a (very) small town – not the inner city or anything like that.

Well, now that I’ve written pages and pages…. There you go! I have a lot of questions and am hoping to get a bit of answers, or at least some more things to think about! Thanks for any input! :)
