Hi Moshe,
G Power has been recommended on this list on a number of occasions. It's free ! There's also a new version out.
To do what you want to do, http://www.psycho.uni-duesseldorf.de/aap/projects/gpower/reference/reference_manual_05.html
However, if you're comparing two sets of data in a correlation, a priori you expect some sort of correlation, and it would be unlikely not to get a favourable p-value......does it mean anything ? So, are you sure you want to do this ? Isn't it the r-value that's important, and how the data are affecting that (scatterplot).
Best Wishes,
Martin Holt
