I recommend PF Tempesta Five. (Normal, not condensed)
Pixel font with easily readable characters and numbers while still maintaining the same height as the normal fonts (hooge, etc).

It also features all the custom chars that is usable in a wow character name.
One thing though. I had to open the font in a font editor to reduce it's height a little bit as it was placed 1 pixel higher than my normal font. If you have no problems setting the yValue of the setpos -1 then you shouldn't need to do this.
