As for the names: hover over one of the graphics; after a moment, a "tool tip" box should appear containing the name of the smiley.
Yeah, I know. I prefer to see them all at a glance, no mousing required. I do wish there were many more to choose from. Smilies can convey intent, especially after people get used to seeing them with the names listed. You learn them and retain them better that way.
