the above MIME structure looks okay I think, but I can't tell if the
encrypted blurb is in the correct format in its decrypted form.

ie, when you decrypt the blurb, it needs to be a MIME part.

the extra blank line above should not exist. but there *should* be a
blank line *after* the Content-Type header.

where's the Content-Type: application/octet-stream header go? :-)

it needs to be here.

can't tell if the encrypted blurb is in MIME format.

I suggest you read http://www.ietf.org/rfc/rfc3156.txt
