Because the equation W=D*U must ALWAYS stay in balance, if the task type is Fixed Units and you change the units anyway, Project has to decide whether it's the Work or Duration that must also be adjusted. Since it's more common for the work to be constant in the real world (it takes the same amount of work to paint 100 square feet of wall regardless of how fast or slowly the painters work on it) the default behaviour in the scenario you pose is to treat the task as if it were Fixed Work and change the duration. This doesn't have anything to do with effort driven or not - the settings of effort driven versus non-effort driven only come into play when you add bodies to or take them away from the task - when editing the resources that are there without changing the actual number of resources assigned the effort driven setting are ignored.
Idiot proof templates in project management are an impossible dream. The function of Project is to help decision makers predict the outcomes of their decisions. It is not a clerical tool and cannot be used passively - and passive use where you just plug in the numbers for the template to massage while the template designer has done all the brain-work is what templates are all about. Because it is such a powerful tool, the only way to idiot proof it is to make sure that idiots aren't expected or allowed to use it. And that means the people who will be using it need to be properly trained, not only in how to "work the software" but also how it fits in the overall managment strategies of your organization. I'm a very strong believer that skills in Project cannot be learned by rote memory of procedures in "how to use the tool." Giving someone MS Project who does not have some understanding of PM principles, some of the WHY Project works the way it does, and how project managment methodology should be applied to meeting the objectives of the firm is tantamount to giving a child a loaded gun to play with.

This has now thrown up another interesting development.
With the Task Type set to Fixed Units if I adjust the %effort on the
assigned resource it increases the duration to reflect this new percentage
automatically. This doesn't happen if Task Type is set to Fixed Duration but
of course this has the other problem that we discussed with splitting the
task. Do you think there is a setting to avoid this. Effort Driven is
unchecked btw.
This isn't as serious as the last issue as you can simply adjust the
duration back to what it was originally but it would be nice to set it up
properly so giving less to worry about in adapting processes to circumvent
it. Bearing in mind I need the templates to be fairly idiot proof.
Thanks,
Andy.
