One of the purposes of Personas is that it allows you to build screens that match what you and your users need. By all means look at what others have done to get some inspiration. That's especially helpful when you are starting out. But do make sure you do all of the necessary research to discover what is going to work best for your users - it will almost certainly be different from what other people have built for the same transactions.
While you are doing that research, you should take the time to learn how Personas works for yourself. Even if you use somebody else's flavour as a starting point you will most likely need to change it. There's plenty of content here on SCN explaining how it works - start with Getting Started Guides and them move on to the rest of the Personas Wiki.
