I meant to paste in an example of a manual polar plot, which has most of what 
I want except for the gridline labels:

  PolarPlot[6 Sin[x + Pi/2]^2 - 2x, {x, -Pi/2, Pi/2}, PlotStyle -> {Red}],
  PolarMap[Identity, {0, 7}, {-Pi/2, Pi/2}, PlotStyle -> {GrayLevel[0.5]}],
  PlotRange -> {{0, 6.25}, {-3.50, 2.00}}, AspectRatio -> Automatic]
