It sounds like you're seriously confused. Plugin making is damn easy compared with real programming; most folks have no problems. Basically, you need said EV/O templates, and you need them open in ResEdit at the same time as you are editing a plugin. You don't need to choose open with templates - all you need to do is double-click on the resource to open it. You also need the EV/O Bible - a good, DocMaker, annotated version can be downloaded at the (url="http://"http://lemmings.tsx.org")Lord of Lemmings'(/url) website.
