I'm guessing you're splitting up the files because it hits a little above our attachment limits. BTW, when did they stop the .r00 .r02 extensions in the rar format? Had I known that, I would not have tried to open the second part only to get a CRC error when it worked just fine from the first file. 7-Zip is an odd critter for that one.
Okay, at home, I appear to have all the fonts installed, because I don't see a trace of those missing characters boxes. And I can't find the odd page break issue with the image, so either Open Office handles the file better than Word 2007, or not having the proper language support screws up the page layout a bit. Only way the former could be true is if MS broke handling the older formats in Office 2007 in a post retail patch however.
