Word "Save As" HTML gives bloated files, but these days the sizes involved are unlikely to be a concern. The internet is about information at its best (and often misses the target). So I say make sure the page is accurate and readable. Which it looks like is being done.

PDF is a bit of a pain, consider doing it with anchors and a list at the top. Or Pages with a heading of links to each page. Not sure if Word handles anchors well, but links are no problem. Might I suggest that you don't change the URL of any page, give them appropriate names then have an (edited) "latest.htm" with links and leave old ones as is. That way people can put them on their favourites and always get back to them without searching!

Once you go down the Word route - don't try and see what it does in the HTML. Even a power user of HTML would give up on analysis. Trust me.

You can clean-up Word HTML (ish) in Dreamweaver, but don't expect miracles!
