Key editor

[Søren Hansen]

When I'm in the key-editor (gpg --edit-key <key ID>) and do a 'list' i
get this:
#######################################################################
pub  1024D/E8BDA4E3  created: 2002-02-22 expires: never      trust: f/u
sub  4096g/7EDF358D  created: 2002-02-22 expires: never

(2)  Soren Hansen (Work e-mail) <shansen@end2endwirefree.com>
(3). Soren Hansen (Secondary e-mail) <sh@freesite.dk>
#######################################################################
What does the dot after "(3)" mean?

When I run 'gpg --fingerprint' my secondary e-mail shows up first even
though it's the one, that I added lastly:
####################################################################

     Key fingerprint = 196A 89ED 78F3 9047 2A36  F327 A278 DF5E E8BD

<shansen@end2endwirefree.com>
sub  4096g/7EDF358D 2002-02-22
#####################################################################

Does it matter in any way whatsoever? If so, how do I change it back to
sh@warma.dk?

Another thing: I've generated a new key (because I had a ridiculously
low lifespan on the previous key).
Naturally, I'd like to keep the old one to be able to read e-mail
encrypted with the according public key.
But I do not wish to use the old key for signing or encryption anymore..
I've done this:
1. I generated a revocation certificate, and imported it.
2. I sent the revoked key to a keyserver.
3. I used gpg --edit-key to disable the key. When I try gpg --edit-key
on the old key it tells me that it's disabled, so all is good.
4. When I run 'gpg --sign' it still asks for the passphrase for my old
key. Why?
