What's the difference between LittleBigPlanet 2 regular vs Collector's Edition?

I'm looking forward to buying LittleBigPlanet 2 until I verified there were to kinds. The standard and collector's edition. I bought LittleBigPlanet 1 Game of The Year Edition and noticed it had free downloaded content. I also know the regular LBP doesn't have them. Now I want LBP 2 and on Amazon I saw LBP 2 and LBP Collector's. What's the difference? And be specific. Also, I downloaded the demo and noticed the costumes on LBP 1 were available. Will the be available on LBP 2? Not new stuff. My Sonic, Marvel, and Watchmen costumes. Will they transfer to LBP 2? Please help me!!! O, and I not old enough to have a job. My parents are funding me. THX
