If it looks like good content link to it... isn't that what the "web" is all about? ;)
You may wish to do a quick look over the website to make sure they aren't doing any shady SEO.
I believe that Google will compare your site with the patterns.
In other words, if your links to PR0 are organic, on topic and there are few of them, I believe that there is no harm to link to PR0 pages. It may be even indirect benefit in avoiding the over optimization filter. However too many links to PR0 pages look suspicious and unnatural and, I believe may trigger the spam filter.
In other words the best strategy probably will be to think rather about your visitors' satisfaction than about Google.
