In the newest pstricks-add, there are some new macros (\pscurvepoints, \pspolylineticks) that give more options for ticks and arrows on parametric curves, Some examples are  given in section 26.3 of pstricks-add-doc.pdf. You'll have to update to the latest versions of all the basic pstricks packages (pstricks.tex, pst-node.tex, pst-plot.tex, pstricks-add.tex) and their associated .pro files for this to work correctly. These are all on ctan.org, and, more directly, from http://archiv.dante.de/~herbert/ .
