Regarding font size, it's an option setting. I use smaller font sizes personally, but just a matter of preference. You can scale the font though if you prefer larger fonts. We are using a non-standard font I believe. Not 100% on that though, we had a custom one built, then used a licensed one, not sure what we stuck with off hand. I believe in the Hero's Journey reference there is reference code to font scaling the nameplates, but I'm not sure on that.
Here's an example of text scaling, the first in a tiny size and the second in a largerer size. I wanted to have those at the same angle, but unfortunately I was in fly mode and after dropping my character back down to earth the angle changed a bit. Please excuse the up close zoomed images here, but for the purposes of this example they work.
