For user settings, you typically apply GPOs with user settings to OUs containing the users you want the settings to apply to. It's possible to use Loopback processing of Group Policy to have a GPO with user settings applied to an OU with computers and still have the user settings apply to the users logging into those computers. Without loopback processing, the user settings would not take effect. You'd usually do this if you have an OU with computers and you want some user settings to apply to users logging into them, but those users are in a variety of OUs. This feature mainly just provides flexibility, and what you do will depend on your OU layout and other considerations. Loopback processing might be useful for you, depending on the OU layout. For example, your users might be in a variety of OUs (like in OUs for each department), and you might have an OU with the laptops you want to apply wireless settings. In this case you can just apply a GPO to the laptops OU, enable loopback processing, and everyone who logs into a laptop will get those settings. The alternative would be applying the wireless GPO to all users, which might not be what you want.

For example, say that you have configured the user to allow changing the desktop but restrict the computer, even though the user can change his desktop on every other computer, he won't be able to on that one.

Not all user policies have equivalent computer policies, and I don't think there is a computer policy for desktop wallpaper. In the case that want to enforce wallpaper on some computers, you could create a GPO with the wallpaper user policy configured along with loopback processing, and apply it to the OU/Site/Domain containing those computers.
