Stu,
A few details about you will help gain advice here - weight, surfing/sailing history, budget, age/height (not as important) and amount of w/surfing you plan on doing.
The funster is a good starter, and you'll probably have a ball on it. The Xcite is a good allrounder, and if you get your feet on the funster, I'd be looking at about a 120-130lt Xcite (or similar) board from there. From there, the JP freestyle wave would be a good wave board, but it's probably too big of a skills gap if you go directly from the funster and you might get frustrated without a middle-range board to help you progress. There are also plenty of other boards in other brands without being brand-specific.
Wave-wise, you can ride anything on a wave, and although I'm not very experienced wave-wise, I'd assume that but if you want to progress to wave-specific windsurfing then you'll be looking at a small board so will need to get your skills up before taking that leap. You'll need to waterstart fairly well, gybe/turn, and confident with balance & rig handling. In saying this, if you're committed to it, it won't take long. Good luck!
