What I recommend is to start out with simple abs and cardio for the first few weeks (only work your abs once or twice a week though) then when you're ready, you should try to do some full body circuits. I'm going to get killed for this, but when you get over the fact that his veins may explode on video, Scott Herman gives some decent, if not good advice. Look into his full body circuit routines.
Furthermore, your body is made in the kitchen. For example, since I stopped eating shit and limited lean dairy, I've never felt better. I'm not sure about your dietary needs, since everybody's different, but at 5'10", you probably are going to aim for something like 150-165 lbs. So try to eat 1800-2000 calories per day, high protein (which on the college student's budget means nuts- especially almonds, ala-fortified or wheat pasta, brown rice, lean food from the cafeteria) whole grains and healthy fats.
Excuse me while I creep real quick. Your profile says that you're a student at WOU, so I took a look at the cafeteria menu. For tomorrow, for example- it says that the cafeteria over there will be serving some kind of casserole, sicilian vegetables and herbed foccacia bread as well as SW chicken salad. Take the sicilian vegetables and sw chicken salad. Tomorrow night, take the cod, rice pilaf and the roasted vegetables.
I hope that helps. Oh and one more thing- some motivation. This is what happens if you sit on your lazy ass for too long:
