polar(theta, r)
gca().set_thetagrids([])

If they are all the same kind of points--all markers, for example--then 
I would expect the rendering order to be the plot command order, because 
each plot command adds a line to a list of lines to be rendered.  You 
can control the level using the zorder attribute.

lines = polar(theta, r, zorder=2.5)

or

lines = polar(theta, r, theta2, r2)
zo = lines[0].get_zorder()
lines[0].set_zorder(zo+0.1)
