How long will it take me to get in shape?

I'm 17 and 2 yrs ago I went vegetarian and started counting my calories and lost 50 lbs. While I was losing my weight, all I did was walk for exercise, but for the past 2 months I have been going to the gym and taking 4 cles which include 30 minutes of kickboxing cardio cl, 30 minutes of an abs cl, 30 minutes of what is called "boot camp", and 30 minutes of relaxation yoga. That gives me a total of 2 hours of working out and I do this every Monday, Wednesday and Friday. That 6 hours a week. I'm weighing 125 lbs. and I may need to lose 10lbs max (I'm 5"3) but mostly I'm just wanting to get a really tight and in shape body. Do you have an idea of how long it will take to get in the shape I'm wanting to be in, what foods I should be eating and how many calories/carbs whatever it is I need to be watching to maybe lose a few lbs and tone up/build a bit of muscle?
