I recommend looking in your area for private lessons with an instructor who is experienced in working with/around your type of injury. Ideally you should be able to work around the injury while healing, and then as you progress with your PT/rehab you would be able to gradually incorporate the areas you have been working around.
I'm personally biased towards classical pilates -- there is a listing at www.classicalpilates.net
I've also heard good things about Stott Pilates, but don't have personal experience with it.
As for books and videos, I just flipped through one of Alycea Ungaro's 15 Minutes Everyday Pilates w/DVD and I think that will probably be my next purchase. Has great pictures. Brooke Siler also has some good books out.
The Mari Winsor DVDs are not bad. Borrowed some from a friend once -- didn't really care for the slick production values, as it seemed styled to appeal to people who jump from one exercise fad to another, but the actual workouts were paced well.
What you would miss by only working with books and DVDs is that you would probably only be able to do mat work. Nothing wrong with that, but if you go to a pilates studio there are apparatus that you can work on, which gives you more options in terms of support during certain exercises as well as additional challenge/resistance for those exercises where you are able to isolate your ankle from what the rest of your body is doing.
