I don't have the answer to your question, but just this:
you might want to have a look at the MetaPost Preview macro's for 
WinEdt, you can find them on 
<http://www.winedt.org/Macros/LaTeX/MPPreview.php>. In short, they 
compile metapost docs to viewable .ps output. For now, they don't do 
everything you describe, but I'm planning to expand their 
functionality as soon as I get some time.

Wald
