How everyone get started??

Hey everyone, I'm new to this board and wanted to get a little advice. I am finally going to learn to wakeboard this summer and I have a few questions...I can water ski and snowboard pretty well already..
- I am looking at the Liquid Force Nemesis 131, I am 5'8, 138 lbs. It's great price and thought it would be good to start with without a big investment. Any thoughts on the size and board??

- How did you learn? My husband skis and I will be the only one that wakeboards? What's the best way to progress if I don't have people around to teach me?

- One other thing, I fractured my tailbone around March 1, buy the time we get on the lake, I should be better, but do you think there is a lot of risk of reinjury??

Thanks! I know I had a lot of questions, any info will be helpful!
