Excellent idea!

All of the above. ;-)

More serious:
email signature - Doesn't make much sense, if you sign all your messages 
because the fingerprint is implicitely included in the signature. More 
precisely, the long key ID, i.e. the last 8 bytes of the fingerprint, 
are included, but that's sufficient.

business card - This makes sense.

letterbox - Probably not.

T-shirt - This is a cool idea if you go to a fair which is attended by 
other people using OpenPGP since those people might ask you to sign 
their key in exchange for signing your key. Of course, you'd only do 
this after thoroughly verifying the identity of this person. Other 
people might ask you what the number means and then you can start a 
nice discussion about privacy, encryption, Vorratsdatenspeicherung, 
etc., with them.

What do you mean? If you have specified your signing key (which you 
appear to have done already) then you can attach your public key with 
Attach->Attach My Public Key. It's not necessary to attach your public 
key to all messages. Instead you should upload your key to a key server 
(which you have done already).

Yes. See http://www.g10code.com/p-card.html. The FSFE offers such a card 
to all of their fellows (http://www.fsfe.org/en/card).
