Yes, they are very easy to set up. Once you have a user made for him in the Users menu log in as that name and go to the "Sign Up for the PlayStation network" icon in the network section. You'll need a separate e-mail address for his account. When it gets to asking what type of account select 'sub account" and it will ask for the master account log in to tie it to (your account). Other than that it's all about the same as when you set up your own name.
