I don't have the SDK so I don't know the capabilities of using templates to customize the generated code, so here's my questions:

1. Can I edit a template?

If so...

1. If I edit a template to, say, include another user defined code region, and a bugfix release comes out that includes changes to this same template, will I lose the changes I made?

Yes, they're just text. Customers even have a full blown IDE for that

Templates are bound to templateID's. These bindings are defined in a templateset config, which you can find in each driver's templates folder. (CSharpTemplateset.config etc.)

If you create a new templateset config (it's just xml) and bind an id to your custom template, newer templates won't overwrite your own. You do have to migrate your own to the new template though. However most of the time, bugfixes to templates are not very common, and extending templates is mostly done by include templates, i.e. binding a template to one of the include template id's discussed in the documentation ("Using the generated code -> Adding your own code to the generated classes")
