Hi Fletcher...
For me the ability to both ride and judge waves properly came first...once i had that waxed i started trying spins and rolls...practice makes perfect and like Hugh says you will probably land up doing flop rolls and lame spins before you get the hang of it.
My advice would be to surf as often as possible to get fit and gain a better knowledge of the sport, watch the more experienced boogers taking note of the execution of the moves and on which part of the wave they are doing them...
Keep at it and remember...it's about progress - not perfection!
There are a few websites with info on doing moves...check out
