Outlook – How to convert .eml files to PDFs

I have almost 300 e-mails in .eml format that I need to convert or print to PDF for legal purposes. Because of that, I have some pretty specific needs:

1. Must have page numbers.
2. Must NOT have other headers/footers (especially not the path or current date).
3. Must NOT show BCC recipients in the printout.
4. Must have at least to, from, cc, and subject.
5. Must not display user/profile/account name across the top (a la Microsoft Outlook Memo style)
6. Filename must be the subject of the email, with some kind of unique index inserted or appended to prevent overwrites.

What I've tried so far (and why it didn't work):

1. Printing to PDF from Outlook. Always prints with my name at the top.
   I accidentally discovered at home that if you open the files with no
   account set up, you can print them individually with no name. But
   there doesn't seem to be any way to import them into Outlook itself
   to print them all at once, or, at least, in larger batches than one
   at a time. Even if I were inclined to print them one at a time, the
   job name/filename that Outlook seems to default to for print-to-file
   jobs is "Microsoft Outlook — Memo Style" which is no good.

   Side note: I have access to three different PDF printers at home:
   Microsoft Print to PDF, Foxit Reader, and PDFCreator. MSPTP doesn't
   offer a default filename at all, and the other two use the one I
   mentioned above.

2. Import them into a Thunderbird local folder using importexporttools add-
   on. This may be my best bet, but the issue that drives me nuts more than
   should be able to use importexporttools again to save the files, en
   masse, to PDF, but any I save to PDF in this way have the default
   headers/footers on them. I have scoured the config files and set up
   inside and outside of Tbird and I cannot for the life of me find
   where it's getting that setting from. The alternative is to save all
   300 one by one by one. But even if I'm up for that, Tbird prints
   either scant headers (I think it consisted of from, date, subject on
   print.show_header = 0) or the whole thing– there's no inbetween.
   Frustratingly, no difference between "normal" headers (1) and full
   headers (2)– they both seem to print the full header. So if I go
   this route, I will have to go through and manually remove any BCC
   lines from the PDFs from about half of them, give or take.

3. (Added since original post) Changing the extension to mht and
   opening in Internet Explorer. Tried opening in Firefox, too, for
   good measure, and Chrome. IE looked good, and the footers and
   headers were formattable, but all the email headers were completely
   missing. Firefox wouldn't even open it, handled it like a download,
   and Chrome it was just the plain text of the body on one long line,
   no formatting, and no headers. Just to cover all my bases, I tried
   the eml files in all three browsers, nothing.

Anyone have any ideas?
