Why not just peruse sailnet? There are plenty of good threads with info on anchorages/mooring fields, dive spots, beach bars, etc. There are also suggested itineraries for your cruise around the islands. Depending on when you go, will also affect where you go. If the Winter, the swells may keep you out of Cane Garden Bay and make things uncomfortable @ Cooper Island. We've only gone in the late Spring and when I saw this video of Cane Garden Bay, I couldn't believe it was the same anchorage.
