Hey bud, I was in Army spec-ops for years and I can honestly tell you that only about half of what you have listed will help with getting you ready for SEAL training. You should scratch all the basketball stuff, and probably the martial arts stuff as well. Not that you should quit, just saying that it won't help you that much.
If you hang around this site for awhile and prove that you're serious, I can email you a fitness training program that is used by the Special Forces to get their trainees prepared for the SF Q course.
Essentially, before you even step foot near a SEAL training facility you need to be able to do about 100 pushups in 2 minutes, 100 situps in two minutes, be able to run 2 miles in under 12 minutes, and be able to keep a 8 minute mile pace for distances as long as 7-10 miles. Oh, and be sure you can do about 30-50 pullups straight, or at least be able to continuously do pullups for 60 seconds straight without dropping from the bar. Road marching with ruck-sacks weighing in excess of 100lbs for distances as long as 15-20 miles is also standard.
Again, if you're serious stick around and keep in touch with me. I'll help out any way I can.
