I have never used FCX (Only Pro), but the method for the titles should be the same. Yoou can add text by bringing down a pulldown menu in the video canvas. It should have an icon that looks like a filmstrip with a letter on it. Select text->text and you can put in details, change font etc. There may even be a text tab (I don't have FC in front of me right now so I'm trying to do all of this from memory). Again, in wireframe mode you can move the text around. If this is something that you will do often, I recommend that you not what your shift in the y valud of the text is for future reference.
Tell me if you have any problems with my instructions, and I should be able to pull up FC and have a look then. Good luck.
