First steps with GPG, am I off to a good start?

[Robin Kipp]

Hello all,
I'd like to get started using GPG on a regular basis, e.g. to sign my EMail messages and exchange encrypted messages with a few people. So, I just generated my first keys in this manner:
1. Booted to a secure system.
2. invoked GPG using the following command:
gpg --expert --gen-key
3. Generated an RSA key with signing and certification capabilities and 2048 bits in length.
4. Edited the key using gpg --edit-key in order to add all required UIDs.
5. Invoked addkey to generate a 2048 bit RSA sub key, with encryption and signing capabilities.
6. Exported all secret and public keys to a secure medium, also exported the secret sub keys.
7. Rebooted to my production system, imported the public keys and the secret subkeys.
The listing now looks as follows.
For public keys:
MacBook-Pro:~ robin$ gpg --list-keys DC329876
pub   2048R/DC329876 2013-10-10
uid                  Robin Kipp <robin at robin-kipp.net>
uid                  Robin Kipp <mlists at robin-kipp.net>
uid                  Robin Kipp <robin at debspace.org>
sub   2048R/77DFFF08 2013-10-10 [expires: 2013-11-09]

For secret keys:
MacBook-Pro:~ robin$ gpg --list-secret-keys DC329876
sec#  2048R/DC329876 2013-10-10
uid                  Robin Kipp <robin at robin-kipp.net>
uid                  Robin Kipp <mlists at robin-kipp.net>
uid                  Robin Kipp <robin at debspace.org>
ssb   2048R/77DFFF08 2013-10-10 [expires: 2013-11-09]

I'm signing this message using this subkey - and since this may not be widely available on keyservers just yet, the public key is at the end of this message.
Could someone on this list perhaps be so kind and see if I've made any mistakes? I set the subkey to expire in a month just incase something went wrong with it, as I'd like to get it right before starting to effectively use it…
Many thanks for any help!
Robin
