How old are your fruit trees? If they are still young that may be why they are not giving a lot of fruit.....I have always found fruit trees a bit less than reliable - some years I had a glut and the next year hardly anythiing.Even other friends say the same thing so it is not only me. Mind you we do all live in Scotland and sometimes the blossom can be caught with a late frost.
As far as your borders go, you will have to bear in mind the depth of them and plant accordingly. Smallest shrubs like the small hebes would so and are evergreen, as is euonymus. Fill around your shrubs with some perennials but don't crowd the fruit trees. They will need all the goodness and rain from the ground that they can get and don't want to be fighting with other plants for it.
