I second that.  Have you read any of the natural language processing 
reasearch in this area?  There are a variety of English parsers already 
available?  Googling for "charniak parser" or "collins parser" should 
get you something.  I believe Dan Bikel has one too.  Those are trained 
on Wall Street Journal text.  You might also look into Minipar, which is 
rule-based and not as WSJ specific.
