On the PS3 XMB go to Account Management> Reedem Codes. Simply put the codes from the back of the game manual not the red card. If you already have the beta phase 4 client you don't need to reinstall it, just select "back" once you enter the code. This saves you time re-downloading everything, regardless it doesnt hurt either way.

Also, very important make sure when you are asked to assign the service to be on the account which your characters are on, DO NOT make a "new service account" your 1.0 characters will NOT be linked to it. Just be extra careful, I was much too excited the first time and made this mistake. I had to go buy a new copy of the game. SE customer service is way too busy and will not be able to help you in a timely manner...

Have fun, see you in game =)

EDIT:

The 30 sub comes with each new registration code you attach to your SE Service account.
