Hi Ray,
     I know your pain.  It took me two years to get mine running right. Here
are some links to web pages that explain a lot about what is going on in your
AC system:

     If you need some basic parts, the guys at AMA are great.  They were a
huge help to me, maybe over the phone they can help. <A HREF="http://www.ackits.com/index.htm">AMA Inc. Automotive

     Also, if your hoses go bad, NAPA can make new hoses with your old
fittings for around $50.  Cheap.  Feel free to write back with any questions.
