want to make simple change to header menu

Using v.1.5.0.

Client wants the "home" link at top of page to go to her web site, and to change the "home" link to "storefront". I've searched and found some tutorials for "adding additional links to headers and footer", but I don't see in THOSE instructions how I would change "home" to "storefront".

My second idea was to turn off that top menu bar, and use all ez pages for links. But creating ez-page links makes them appear below the page banner, which I guess would be ok if I could figure out how to make the font white, and also to avoid confusion I'd probably want to remove the "home" and "log in" at the top of the page.

I assumed, wrongly, I think, that that top menu there is "breadcrumbs" but when I turned OFF breadcrumbs those links are still there.

define('HEADER_TITLE_CATALOG', 'Home');

Thanks for that info. However, I still do not know how to change the "home" link to link to her website. Also, she does not want to have regular customers to have to log in, but wants that "log-in" link for a special class of customer called "wholesale log in". Maybe this is really 2 different questions.

re: the above message regarding having the home link redirected, I've decided against doing this, so please disregard the message. I tried to edit it and remove, but too much time has elapsed.
