R help - Jun 2012 - Biplot - how can I make it more readable?

Hello,
I am doing a principle component analysis on a dataset with a lot of 
different variables and have constructed a biplot of the data. 
 Unfortunately, as can be seen on the attached image, the biplot is very 
messy, cluttered, and hard to read.  I have performed a few modifications 
including outlier removal from a few of the variables, which has made the 
plot better, however it still is too cluttered to read the variable names. 
 Is there any further improvment that can be made to the attached plot and 
if so what steps should I take? 

Thanks, 
Derek
