In reality, unless your a competitive bodybuilder its not absolutely neccesary to eat 6 meals a day. Basically the idea is to just eat as frequently as possible to keep you body in state where it's using, not storing, the nutrients your taking in.
as far as a workout program goes theres really too many to list in one response. i would search for workout programs, and try a different one out each week to see what works for you. It will be fun trying different splits/reps/exercises, it will keep your body guessing, and along the way you'll find exactly what your looking for.
As far as cardio goes, some people do it in the morning, then come back and do weights at night, some do 30-45mn after weights, some do it on a whole seperate day, etc, etc. The main thing is to just do it, but not immediately before weights, you need your glycogen stores lift weights, doing the cardio before weights will strip you of much needed strength.
And, im assuming your female, contrary to popular belief, weight lifting will not make you huge as a female you will just get more toned the more you lift, you wont look like Chyna from the WWF, she did more than just pump iron...
