JSF has actual menu and tree tags to do that. Not in the core tagset, but in the various extensions like Tomahawk, RichFaces, IceFaces, and so forth.

As a general rule, you shouldn't put JSTL tags in a JSF view. You shouldn't have to. And in the case where you're actually putting logic JSTL in the view, you shouldn't. Period. It violates MVC.

Well, if you tried, you could probably intermix COBOL code in with JSF. But just because you can do something doesn't mean it's a good idea.

Every framework tends to influence the shape of its projects. Good frameworks are flexible enough that the end user can't tell which framework is actually being used, and JSF is fairly good about that (except for the URL issues).
 
Don't get me started about those stupid light bulbs.
