Googles new NOFOLLOW and how to use it 0

Hi all,
as you all sure heard google changed how the nofollow works. So in the past it worked like that:
if you had 10 links on a page and 5 of them were nofollow then each of the do-follow links would get 1/5 of the pagerank of the site. So this way you could do pageranksculpting.
But google changed it all last year. So now it is like this:
if you have 10 links and 5 are nofollow then the PageRank is still devided by 10 and every one of the do-follow links gets 1/10 of the pagerank.
As Matt Cuts says the PR of the nofollow links just “evaporates” into nothing. So it makes no sense to use them. He also said that you should just let the PR flow in your site.
Well now I have 2 questions about that:
1) OK I normaly nofollowed pages like “contact us” or “privacy policy” because the are not important for search engines. Well this sucks now because I have them on every page and with the nofollow not working anymore the get a lot of pagerank from every page.
For example if you have an inner page, that only links back to the frontpage and you have 5 links sitting in the footer to pages like “contact us” then the only important link to the frontpage gets 1/6 of the PR.
What I do of course is to add the “noindex” Meta Tag to those unimportant pages like “contact us”.

Now the question: As google does not index them I think all the PR they get will be lost. Is this correct?
2) How are the links on a page counted? From the examples above I said the page has 10 links. What if 8 of the links pointed to the same page of the site.
Would this site get 8/10 of the PR or do all the 8 links count as 1 link because they point to the same page and so the PR going to this page would be 1/3?
