im gonna go right ahead and tell you... ok...
find a picture that you want on the internet, (google works good)
and then paste it into photoshop (ctr + V)
after that select the part of the picture you want by either using lasso, and magic wand to select the parts you want to delete, or follow this tut i made telling you how to blend it into your background:

and for my name, all you have to do is use the text tool, (the T) and type your name, then look up a tutorial on text
hope that helps
