try the pstricks-add.tex from http://perce.de/LaTeX/pstricks.add
and
\psaxes[linecolor=lightgray,ticksize=-4pt 0,
	showorigin=false](0,0)(-4,-4)(4,4)

alternative you can do

\psaxes[linecolor=lightgray,ticksize=-4pt 0](0,0)(-4,-4)(4,4)
\psaxes[linecolor=lightgray,ticks=none](0,0)(-4,-4)(4,4)

no, but you can use \multido and write the label.
