Good comments, and thanks for the suggestions. I'll check out MAFF and MHT. PDF is not in hypertext context, i.e. not clickable and page requisites not viewable as individual files, so for my purposes. doesn't do the trick.
And, yes, scrapbook allows editing of archived pages, something I'm generally not interested in (being an archivist :), but something very powerful indeed.
I am pretty much stuck on Scrapbook -- because it saves the page in hypertext context, with all links etc. What I don't like about it is that it edits / modifies the original html code, so it loses its "purity" from an archiving perspective. Better from this perspective: WARCreate:
http://warcreate.com/. Much trickier to get running, however.
Most importantly for these purposes, Scrapbook generates a reliable permalink based on the timestamp (i.e. timestamp/index.html) which makes the whole "save a link to an archived web page" macro work pretty much flawlessly. Three clicks: one to scrapbook, two to open scrapbooked page (doubles as a check on archiving), and three to highlight timestamp. Then, a copy, and paste into macro.
Future: Someone more clever than I could probably manipulate Scrapbook to automatically push the timestamp of the last scrapbooked page into the buffer, and generate macro text -- much the same way that Dropbox will push a link to a screencapture into the clipboard buffer for immediate pasting. Similarly, Jing will allow customization of the text pushed into the clipboard (I've used it to generate text that is a TW macro), but that is far beyond my abilities to code.
