It should be pretty much the same way. I don't have WP in front of me so I can't take you through step-by-step, but...
Once the font is imported, it should appear in your list of fonts on the formatting toolbar - the one with bold, italic, etc on it. If you don't see any of those, go to the View menu & look for toolbars. Make sure the formatting one is checked like the standard bar is - actual names may vary I just can't remember what they are.
Type whatever you want to say, highlight it & then go to the drop down list on the format toolbar & click on it. That should change your text.
You should also be able to highlight the text, right click on it & choose "font". That will open up a dialog box with a bunch of choices of things to do. The new fonts should be listed there as well.
I'll be here for a while if you need more help.
