I need a list that rates the difficulty of a buch of piano pieces?

Can anyone tell me some and where to find them?

You'll need a copy of Maurice Hinson's 'Guide to the Pianist's Repertoire', a rather stout volume...

Here are URLs for the paperback edition:
http://www.amazon.com/guide-pianists-rep...
and the hardback (you can look inside the book here):
