Does anyone have any views on GAC vs bin installs .....I am not technical really but from day one all of the simple "set trust to full" or install in GAC seemed to be slightly missing the point and my concerns were further raised when reading this

I think it might depend on what you are trying to do. If you are trying to access certain admin level stuff in the object model, but the webpart  is running under only a reader role then you will have a problem. You might need to impersonate the webpart to run under an admin account.
