While working towards your biology degree you will probably be taking all of the required coursework for medical school: biology, general chemistry, organic chemistry, physics, and English. Keep in mind that AP credit doesn't count for med school, so you'll need to take those courses even if you have credits (bummer, I know).
Most students take their MCAT the summer before their third year, but you can take it anytime after you've finished the courses mentioned above.
Work hard to get good grades and a good MCAT score, and in your "free" time work on getting some flavor into your application by doing volunteer work or research.
You apply for medical school a year before you hope to attend. The sooner you get your application in the better, as medical schools have rolling admissions.
Working with patients can be frustrating, but for the most part it's very rewarding. It's all about finding the patient population that you like working with best be it adults or kids, the very rich or very poor, the sick or the healthy (don't worry, medical school will give you the opportunity to work with lots of different kinds of patients so you can figure out what is the best fit).
