Myself personally, I don't think that such an addition is really necessary. As it is, you can click on anyone's username within the Other Users nodelet to see their XP level. Also, I don't like the idea of having more text on my screen than I need. The numbers would just make the list look odd and misshapen (sp?).

Now, as I wrote the above, one idea did occur to me. The chatterbox has already seen an improvement that could help with this. If you hover your mouse over the name of the user posting the message (and you use a browser that shows such things correctly), you'll get one of those popup hints saying how long ago that message was submitted to the CB. This is made possible by the wonderful html 'title' attribute. How about placing each monk's XP in the 'title' attribute for each name in the CB?

The only question that remains in my brain now is whether this would create any additional strain on the database. Would another database query have to be executed to get user XP values in the Other Users nodelet, or is this information already loaded and ready to access? If it requires another database hit, I'd lean towards the direction of no, let's not add this functionality. But hey, if it's sitting there waiting for us to use it somehow, I say add it as a 'title' attirbute :)
