I'm 5'5" 145 lbs and ride 134-136 boards, but you're right Dan in that personal preference is a factor as well.
I kind of figured you didn't have many board shops nearby, Jesse. A wider model (i.e.CWB) 134 should work for you, but if you're young and still growing I would suggest bigger.
As for boots, I think you'll like the '06 Transits. They're plenty stiff for wakeboarding and they fit killer. If you have a wide "fat" foot they may not be the best choice, but your "specs" suggest that you don't. lol BTW, I have a 10.5 foot and wear Large.
