Re: Coordinates from an ImplicitPlot

Let's say you have imp=ImplictPlot[...];

First use Graphics[imp] to turn the ContourGraphics object into a
normal Graphics object.
Now with Cases[Graphics[imp],_Line,Infinity] you can collect all the
Line expressions that make the ImplicitPlot.
I don't know what you want to do with the points, but this returns a
simple 'flat' list with them:
Cases[Graphics[imp],l_Line:>Sequence@@l[[1]],Infinity]
