You want R Sanford Martin's book, How to prune fruit trees. If you do some looking, you could get it for less than 10 bucks. You will also want the Western Garden book. You can prune fruit trees pretty agressively. Stone fruit grows on 2nd year spurs.
Where are you? Local university's Ag dept should be able to help you out. Go to the library and take notes, photocopy sketches for trees of interest if you can't find this paperback for a reasonable price, maybe call a nursery
