[pstricks] A problem with "pstricks.tex"

[Zhong]

Dear All:

I am using MikTex to draw a network graph. 
But there is a limit that the diameter of a circle cannot be larger than 40 pt.
So I want to use the pstricks package.

I am using the Windows 2000 system, and a WinEdt + Miktex + gstools package,
There are all installed under the D:\CTEX directory.
I have downloaded "teTeX-texmf-1.0.tar.gz" file from TUG and copied the 
"pstricks"  directory to "D:\CTEX\MiKTeX\LocalTeXMF\tex\latex", 
I also copied the  "pstricks(.pro)"  directory to
"D:\CTEX\MiKTeX\LocalTeXMF\dvips".

Then I tried a sample file with "\usepackage{pstcol}" in the header by WinEdt,
%==================
\documentclass{article}
\usepackage{pstcol}
\begin{document}
\begin{pspicture}(0,0)(14,13)
\pscircle[linewidth=1pt](5.8,5.8){5.7}
\end{pspicture}
\end{document}
%==================

the Latex compiler returned the following information:
---------------------------------------------------------------------------------------

So I input D:\CTEX\MiKTeX\LocalTeXMF\tex\latex\pstricks\pstricks.tex,
it continued as..

But the Yap previewer shows nothing. And when I run the "dvi2ps",
the following message shows:

DVIPS.EXE: ! Couldn't find header file pstricks.pro
=========================================================


So I have two questions here and hope you can teach me how to solve them:
1,  How can I make the WinEdt tool do not ask me such info:
" ! I can't find file `pstricks.tex'. 
l.2 \input pstricks.tex
Please type another input file name: "

2 How can I get the picture I want.

Best Regards
