In the MapServer TestSuite, there is a great example of labeling contours.
This process works well with streets too.

Basically, you are going to specify ANGLE AUTO in the label definition.

I would do some work on the source data... essentially, the labeling is
going to try to label every INDIVIDUAL feature. I don't know that there is a
way to supress duplicates. The easiest way would be to make sure that all of
your line segments that are the same name are "dissolved" into one line.

than one pixel thick?
Sure, you need to specify a symbol definition, either in a symbol file that
you point to in the header, or in the SYMBOL section of the mapfile.
Here's is a simple symbol definition for a line, we'll make it thick in the
layer definition by using the SIZE feature:
SYMBOL
NAME 'polygon_outline'
TYPE ELLIPSE
POINTS 1 1 END
FILLED
END
....(some more map file)
LAYER
NAME "My_Polygon_Shapefile"
STATUS DEFAULT
DATA \My_Polygon_Shapefile
CLASSITEM CODE
TYPE POLYLINE
CLASS
Name 'SomeClassName'
TEMPLATE "ttt"
EXPRESSION ''
SYMBOL 'polygon_outline'
SIZE 3
COLOR 255 0 0
END # CLASS
END # LAYER
Cheers!
