I believe if you handle your redirects correctly, there will be no change in pr or position. I just overhauled a site(300 pg.) and renamed all directories and filenames with no negative effects. I also switched the whole site from HTML to PHP. I was worried but everything went smooth. I also moved the site to a new host at the same time.
Anytime you change content and/or filenames the search bots will need to reindex your pages. It stands to reason that if otnot is overhauling the site and redoing the content - though keeping the same keywords/phrases - then a change can be expected.
If the same KW density and distribution remain then I would expect the rankings to return pretty close to thier former position but alot can happen in the next index update. Just as a quick example - the SEs might change their algo and what positioned the site at #1 nolonger counts and the site falls to #3. Probability is it will change some. IMHO of course. ;)
