After several false starts due to work still being done on the site despite yesterday being the deadline, eventually got a standard WGET of the site. Got over 67,000 files, but a) lots of them still link to the live site with a full URL, despite telling WGET to fix that, and b) MT tells me that there are AJAX files that I won't have because there's no sitemap linking them. Will have to try to address this on Monday.
