How long will it take to advance belts and ranks in Okinawa Traditional Karate?

I just recently began Okinawa Traditional Karate as a 17 year old. I do want to stick with this for a long time. Honestly not to sound arrogant or y but I am very athletic and compete in soccer at the highest level. I learn at a very fast pace and I am training twice a week for about an hour and a half to two hours everytime I train. How long will it take to learn each kata and how long does it take to achieve the higher ranks and belt. Like how long does it take to go from white to the next one to the next one. Also, when do bo's and sai's and other weapons become part of my training? Also, what is the order of belts in Okinawa. Please answer all the questions. Thanks so much.
