Here... someone made an attempt at it and it's fine for "pop" but lost all the grill etc., in the process. Learning CS3 and what it can do is the real secret behind most any (remarkable) finished pic.
Here's 5 minutes of CS3 on this image...
As a professional photographer I can tell you that you can learn techniques in many different places. Youtube has useful stuff, you just gotta be selective. If I were you and I wanted to progress with a BASIC understanding of just what Photoshop can do, I would start by signing up at Lynda.com and going from there.
Good luck!
