Every state road in Florida has been tagged with ref and relation: http://wiki.openstreetmap.org/wiki/Florida/State_road_relations

In terms of reference tagging etc, did you see my custom highway page?

Honestly, I think the rounded rectangle is best for state roads; although they should be, not all state shields are as easy to read, which is a problem on the limited resolution of a map. U.S. and Interstate Highways and county roads should definitely use different shapes - the actual ones, perhaps simplified slightly, are fine. But for state roads, shields like Colorado's and Louisiana's squish the number into too small of an area.

 It would also be nice to see shields placed by relations, so they can be better-spaced (right now, a route split into many ways will have more shields than one represented by one way). I understand this is being worked on but there have been a few problems.
