Well, bit of a grey area... removing fruit will release vigour into the tree, so more leaves and longer branches, but it won't specifically increase the number or spread of branches - and new branches are usually what you want when you are trying to produce a specific shape.
New branches are produced by the buds activated by winter pruning, so that's a job for after December 2010.
In the meantime removing the fruit will help a small tree get bigger, or if it is actually big enough, then thinning them might be enough to get a small crop without interfering with the development of the tree.
I'd recommend thinning all the clusters to a single fruit, then the June drop will remove some more and then you can decide how many you really need.
Summer pruning involves shortening this year's growth in order to encourage fruit buds for next year. It's possible that this might move your plans forward if you can identify any growth that you will want to be still there but shorter and more productive in the new scheme.
