Hi Miyagi and Jaek,
There are a few threads where your concerns have been discussed in general.... If you check out the Beginner Freediving forum/ New Freediver in Training thread you will find some answers to your questions about static tables, C02 tolerance, etc....
Both you guys are young and while you may want to become great freedivers, you have to be really careful about how you go about it. This sport is dangerous, just like skiing, sky diving, rock climbing, hang gliding, etc. At 100ft down you might as well be on the Moon. In fact, if you view training as serious as an astronaut does, you are probably in the right mindset.
If you have specific questions, keep asking them....
The best suggestion I have for you though is to take a class.
www.performancefreediving.com since you are stateside. It is a four day intensive and many of us made it to 100ft by the end of it. Saves you lots of mistakes, wasted time, incorrect or dangerous techniques, bad advice, etc..... They give a thorough review of physiology, safety practices, technical information and training advice. Hard to beat it and you don't have to start at the very bottom.
