I agree ROFR (right of first refusal) will get you. I think most of the time you can get a WDW resort at 7 months (not Dec 1-14 and christmas and may Easter). However, its hard to say what the future holds. With all the new people coming into Disney Resorts at SSR, it may become much more difficult to book in the future.
Spend the extra $10 per point. There are OKW points for sale for $70 per point if you keep you eyes open and just a little more for BWV. Don't be cheap.
