Penalty for underaged drinking in KY? PLEASE HELP!!?

I'm nineteen, from ky, and was recently charged with underaged drinking and possession of an open container of alcohol in a vehicle (the bottle was empty). The violation codes are 02124, which I think is consumption by a minor, and 00470, which I believe is possession in a motor vehicle. These are my first offenses, other than that I am a college student with a clean record. I have a court date coming up and my friend is trying to reure me that all I will be penalized with is community service. However, I'm really REALLY nervous that I will issued a fine or even jail time, will this happen? Will I probably just be issued community service? What would happen if I were to get a second offense (its college, parties happen). As well, do I have to put this on my job applications?
