Should I add 'nofollow' to site wide internal links?

[Pete4]

I am trying to improve the internal linking structure on my site and ensure that the most important pages have the most internal links pointing to them (which I believe is the best strategy from Google's perspective!).  I have a number of internal links in the page footer going to pages such as  'Terms and Conditions', 'Testimonials', 'About Us' etc.  These pages, therefore, have a very large number of links going to them compared with the most important pages on my site.

Should I add 'nofollow' to these links?

Matt Cutts says not to use nofollow on internal links. He says that causes pagerank to evaporate and that Google has made changes so that pagerank sculpting doesn't really work. He is pretty definite about this.

Great thanks.  Can't be clearer than that!
