To change the expiration date of your key you can do the following:
(where $KEYID is the id of your key)
gpg --edit-key $KEYID
Then type 'expire' and press enter
type '1y', to make it valid for one year, and press enter
Then type 'save' and enter again. That should do it.

To use your GPG key for SSH authentication, i'll point you to my blog
post about it:
It contains a few methods on how to achieve this.

Hope this helps,
