Excellent.

Nah. It's KMail that misbehaves a bit. It shouldn't send HTML messages 
unless you explicitly request it. KMail 1.10 makes it a bit too easy to 
inadvertently send HTML messages.

Those two options are unrelated. The "Prefer HTML to plain text" option 
is used when displaying messages. The "Formatting (HTML)" option is 
used when composing/sending messages.

Signing HTML messages using OpenPGP/MIME should work (and it seems it 
did work for you since the messages in your sent-mail folder had good 
signatures). Of course, the signature breaks if, for example, the 
mailing list software removes the HTML part from the message.
