What I do is change the templates, upload the templates, go to module administration and update the module and then I DO NOT LEAVE THAT PAGE where it writes about config settings and templates etc.
Instead I open a new window to see the changes, work further on the files, upload the files and then go to the module admin window and just press F5 (in which case it asks me if I want to resend the POST data, which I will) and woof, the module is updated again.
