If you're having trouble reading Japanese sites due to all of the complex kanji, or wish to have instant access to all the definitions on a certain page, get this plug in for Internet Explorer called jBrowse.

It adds a toolbar to IE, and enables all sorts of useful tools. I assume that since if you're importing FFXI, you have XP, so you can run jBrowse. I don't think it will work on English versions of Win 98/Me.
Kanji being my weak point, I can't begin to tell you how helpful this has been for me.
