Whoops! I wasn't trying to stomp on you, just disentangling the question. Right now I can't tell whether you're asking one question or the other or both.
If your WordPress software is sending people to a particular location, and you have to redirect them, then anything involving htaccess is a bandaid solution. The real solution is fiddling with WordPress so it doesn't send people to the wrong place.
Note that this applies only to redirecting: the URL that they see in their browser's address bar. It doesn't apply to rewriting: stuff you do secretly behind the scenes. (Or that WordPress does secretly.)
