Rich:  You'll have to do it manually with the axes text method.  The 
drawparallels method can only label them where they intersect the edge 
of the map.

Something like this perhaps:

x,y = map(lon, lat)  # get desired location in map projection coordinates
ax = pylab.gca() # get current axes instance
t = ax.text(x,y,latlab) # see axes.text docstring for **kwargs

where map is the basemap instance, and lat,lon is where you want the 
label (latlab) to go.

latlab can be defined like this:

if latval > 0:
    latlab = u'%g\N{DEGREE SIGN}N% latval 
else
    latlab = u'%g\N{DEGREE SIGN}S% latval 

HTH,
