For example, let's say a given page domain.com/PageName.html has toolbar PR and domain.com/pagename.html doesn't ... if all the links are changed to the lower case version, is it reasonable to assume that the PR will get "reassigned" to the lower case page? I would assume yes, but I would be interested to get some confirmation.

If we assume all the PR is coming from internal links, this is a safe bet, isn't it?

But if some of the PR is coming from external links and they are coming to domain.com/PageName.html, will Google pass that PR onto domain.com/pagename.html?

What do you think?
