1.Give access to users
One of the first things you need to do is to give all Windows Live ID users the possibility to log in to your application. It's not mandatory but it is really hard asking for the PUID of all users and manually adding them to your site(s). The PUID will be seen by the user by accessing the Live ID account services at https://accountservices.passport-int.net/ or by signing in so they see the access denied page.

2.
The display name of the user
Once the user logs in to the site the user name still looks pretty ugly - it's just the PUID that is given to SharePoint from the Windows Live ID login service. Unfortunately Windows Live ID only returns one single claim and that is the UPN, which is in the form of a e-mail address. That e-mail address is not even a valid address. You can not expect to get the full name or e-mail of the user from Live ID - you have to implement something of your own OR use the built-in amazing stuff in SharePoint.
After a successful sync you should see that the upper right menu shows the Name that you specified in the user profile.
