3.0 Myspace Tweaks
With the "New Myspace", known as Myspace 3.0, you can not add your own css to your profile. For this reason it is not possible to copy and paste a code to hide comments, friends or any other tweaks that would alter your profile.
You can select what you want to show on your main profile page using the modules section (under change layout) of customize profile. You can drop and drag sections to where you want them by placing your mouse on the top of the section, grabbing and moving.
