The problem is that $notifications_menubits hasn't been set yet when your code runs (hook parse_templates). If you're using 4.1.10, there should be a hook location called process_templates_complete which you could try using instead.

The keys can be anything you want as long as they match what you use in the template. The values have to be variables that has a value at the time you call register() or preRegister(). I think a lot of people who are new to vb have problems because it sort of looks like there's a "language" with a set of values you can use wherever you want, but really the hook locations are specific places in the code, so the variables you have available in a plugin differ and depend on the hook location.
