Hello Andrew,
I am afraid that at the moment there is not much to do. The extra resources are the Google API services that are being loaded as well as a few extra scripts by GEO my WP. However, I have been working on GEO my WP version 3.0 for sometime now. It is a major update and I am rewriting most of the plugin. A big part of it is joining, removing and optimizing the Javascript and stylesheets of the plugin. So this should have some effect on the performance of the plugin.
There is still some work to be done on GEO my WP version 3.0 but I hope that within a couple of months I will have a first beta to test.
So, I apologize for not having a solution for you at the moment. But an improved version of the plugin is under development.
