Once you create a YouTube username, you will not be able to change it. However, if you were affected by the Google+ to YouTube name change, you should be able to edit your preferences for the name displayed in your account settings.
While you're uploading your videos, there should be something like Title...that's where you put the name for your Youtube video.

You can use anything you want. It can be as simple as your name with 123 after it.
You can go to Youtube, Itunes (you have to buy the soundtrack though), and if you have the name of the song type it into youtube and it should be there.
How about I Feel Pretty? :)
Most people use their names.
